30d070be85 CmdPal: fix alt+f4 handling (#49708)
As I threw in
https://github.com/microsoft/PowerToys/issues/49572#issuecomment-5195807441:

Our alt+f4 handling is wack. We shouldn't close the dock when you press
alt+f4 on it, just like you can't close the taskbar with alt+f4.

But also some folks want alt+f4 to quit cmdpal, and some folks don't. So
there's a setting for what happens when you alt+f4 cmdpal.

Closes #38333
Closes #40277
Closes #49572

- use the same title on the File Explorer Add-ons settings page through
`FileExplorerPreview.ModuleTitle`
- add translator guidance to keep the navigation and page-title values
consistent

## Validation
- parsed `Resources.resw` as XML
- ran `git diff --check`
- verified both resource values resolve to `File Explorer Add-ons`

Fixes #24414.

16baa2d676 [Image Resizer] Clarify preset size descriptions (#49694)
## Summary of the Pull Request

Updates Image Resizer preset descriptions in both the resize dialog and
the Settings page from sentence fragments such as `Fits within 1920 ×
1080 pixels` to CRUTKAS's proposed `Fit - 1920 × 1080 pixels` format.
The UI reuses existing localized mode labels and removes the obsolete
third-person resources.

## Screenshots

## PR Checklist

- [x] Closes: #16790
- [x] **Communication:** Implements the pattern proposed and accepted by
core contributors in #16790
- [x] **Tests:** Existing Image Resizer tests pass; the Image Resizer
and Settings UI projects build successfully
- [x] **Localization:** Reuses existing localized mode and unit strings;
no new translatable text
- [x] **Dev docs:** Not applicable
- [x] **New binaries:** Not applicable
- [x] **Documentation updated:** Not applicable

## Detailed Description of the Pull Request / Additional comments

Preset details now use the infinitive resize mode followed by a neutral
dash and the dimensions on both Image Resizer surfaces. This avoids
requiring translators to make a sentence fragment agree grammatically
with the dimensions.

Accessible Settings descriptions use the same wording, and the obsolete
third-person mode resources are removed from both resource sets.

## Validation Steps Performed

- Built `ImageResizerUI.csproj` for x64 Debug
- Built `ImageResizer.UnitTests.csproj` for x64 Debug
- Ran all 149 Image Resizer unit tests successfully
- Built `Settings.UI.csproj` for x64 Debug
- Ran the PR-built resize dialog and Settings page and verified the new
text in both surfaces

bd33911dd8 [Mouse Utilities] Fix Chinese Ctrl translation (#49693)
## Summary of the Pull Request

Adds Simplified and Traditional Chinese translator guidance for both
Find My Mouse double-Control activation options so the localized UI
keeps the familiar `Ctrl` key label instead of using `控制键` or `控制鍵`.

## Detailed Description of the Pull Request / Additional comments

As discussed in
[#46223](https://github.com/microsoft/PowerToys/issues/46223#issuecomment-5189066402),
Chinese users commonly identify this physical keyboard key by its `Ctrl`
label. Translating it as `控制键` in Simplified Chinese or `控制鍵` in
Traditional Chinese makes the Find My Mouse activation options harder to
understand.

PowerToys localized resources are generated through the CDPX
localization pipeline, so this PR expands the translator comments for
both the left and right Control activation strings. The English values,
resource keys, settings schema, UI tests, and runtime behavior remain
unchanged.

## Validation Steps Performed

- Parsed the modified `Resources.resw` successfully as XML.
- Verified both affected Find My Mouse entries contain Simplified and
Traditional Chinese guidance.
- Confirmed the diff changes translator comments only and passes `git
diff --check`.
- No build or automated tests were run because this is a comment-only
localization guidance change with no runtime impact.

## Detailed Description of the Pull Request / Additional comments
This PR fixes a reported critical vulnerability (#46763) where creating
an environment variable with an equals sign in the name reportedly
caused Windows to crash and enter a boot loop upon restarting. During
the investigation of the issue, several other environment variable
constraints were identified as missing, including there being no
prevention of leading or trailing spaces in names (meaning variables
could not be typed on the command line), no combined length checks and
so on. This PR introduces a centralised, robust validation pipeline for
UI and registry writes to prevent entering states which could corrupt
the Windows environment block.

## Changes
### Centralised validation logic
- All environment validation is now inside
EnvironmentVariablesHelper.cs, rather than split between this code and
the UI.
- Both the UI (via model validate bindings) and backend registry writes
now strictly evaluate against the same unified ruleset before applying
changes or enabling/disabling controls.
- Existing methods have been updated to report back their success or
failure, to enable errors to be tracked more effectively.

### Blocked OS-breaking characters
- In response to the user report, the equals character is now blocked
from both Variable and Profile names. `=` being disallowed is
[explicitly
mentioned](https://learn.microsoft.com/en-us/windows/win32/procthread/environment-variables)
in the Environment Variables Win32 documentation, so it's a surprise it
wasn't caught previously.
- All control characters (including `\0`, `\r` and `\n`) are also
disallowed, both to protect the integrity of the environment block and
the rendering of the strings in the UI.
- Leading and trailing whitespace is rejected to prevent orphaned
variables.

### Enforced Windows length constraints
- Variable Names and Profile Names are restricted to 259 characters, to
match the 260-character null-terminated string length limit in the
Windows Environment Variables Editor (via sysdm.cpl) and RegEdit. To be
clear: profile names may technically be longer, but we should choose to
abide by this authoring tool limit to maintain compatibility with other
editors. There was previously a 255-character limit on names in the
code, and a comment indicating this was a registry limit, but that was
incorrect and has been removed. The new limit constant is
`MaxEnvironmentVariableNameAuthoringLength`.
- In the prior code, there was no limit on the length of system variable
names. This was incorrect. The limit for both System and User name
fields is now the identical at 259 characters.
- There is a length limit on the full environment variable entry
`[VariableName]=[VariableValue]\0`, which is 32766 characters plus the
null-terminator. This is now enforced and the constant is
`MaxTotalEnvironmentVariableLength`. (There's no imposed limit on the
number of environment variables.)

### Fixed User Profile backup "overflows"
- Fixed a bug where a user could create a valid Profile Name and a valid
environment variable name, but applying them would silently fail to
apply the profile because the generated backup variable name
`[VariableName]_PowerToys_[ProfileName]` exceeded the previous authoring
limit of 255 characters.
- Backup variables are excluded from the 259-character limit, as they
are internal to the application, but the combined
`[VariableName]=[VariableVavlue]\0` length is still strictly constrained
to the 32767 environment variable length limit.

There are now separate paths through the code to deal with backup
variable persistence and validation.

### UI
- If an applied user profile's name is now rejected because of the new
rules (e.g. it contains `=`), the UI now shows a specific "Profile name
is invalid" warning rather than the generic "not applicable" message
from before, allowing the user to identify and fix the problem.
- Fixed a small issue in the Add New Variable dialog where a vertical
scrollbar was always present. There are other cases where this occurs,
too, but I've left them for a future PR.

<!-- Describe how you validated the behavior. Add automated tests
wherever possible, but list manual validation steps taken as well -->
## Validation Steps Performed

New unit tests project added with coverage of the new validation
functionality.

Also, manual testing...

Manual validation of each dialog:
- Add variable
- Edit variable
- Add variable via Profile Edit dialog

Test against:
- `=` being in either the Variable Name or the Profile Name
- A control character being present in the Variable Name or Profile Name
- Either the Variable Name or Profile Name containing one or more
trailing or leading whitespace characters
- The length of the Variable Name being longer than 259 characters
- The combined length of name + `=` + value being longer than 32766
characters

The dialog tests can be confirmed by checking to see if the Save button
is enabled:

<img width="1099" height="843" alt="image"
src="https://github.com/user-attachments/assets/685e561a-bd8d-4926-b9b2-a61dea4cc96a"
/>

Also confirm:
- An invalid Profile Name is caught. This can be confirmed by:

Editing the JSON file and adding an `=` character in the name:
<img width="497" height="197" alt="image"
src="https://github.com/user-attachments/assets/c6aa5d62-0672-499a-aac4-c639e8158b61"
/>

Then opening the application and trying to enable the profile:

<img width="1117" height="371" alt="image"
src="https://github.com/user-attachments/assets/bd887a44-5e65-4750-9c6f-9bf1b82a5ad6"
/>

Also confirm that in the Edit profile dialog, you can enable the
profile, but the Save button is disabled:

<img width="688" height="603" alt="image"
src="https://github.com/user-attachments/assets/10d186d9-17a0-4210-93e3-23b1e2723f5f"
/>

- Confirm that control characters cannot be part of the Variable Name:

First, run this from PowerShell, which adds a string containing the
newline character to the clipboard:

```pwsh
Set-Clipboard -Value "MyVar`nName"
```

Open the Add or Edit variable dialog and paste the value into the Name
field. Confirm that the character is not pasted and the string truncates
before it:

<img width="1424" height="732" alt="image"
src="https://github.com/user-attachments/assets/260ff728-57a2-438f-bb66-08d32a327b64"
/>

(For the null character specifically, use `Set-Clipboard -Value ("MyVar"
+ [char]0 + "Name")`.)

- The initial dialog button state. Re-open the Add New variable dialog
multiple times and confirm the Save button is disabled each time before
making any input.

- In the Add/Edit Variable dialogs, enter a valid variable name and then
clear it, confirming that the Save button enables and disables
correctly.

## Still outstanding

There are some flaws I've found which I'm choosing to leave for now,
mainly for expedience so the above issues can be prioritised:
- Handling duplicate profile names - there is the potential there for
duplicate variable names under identically-named profiles to conflict.
- Profile JSON import is still not sanitised.

These should be added in a future PR.

1703e7ac09 [Build] Fix UTF-8 and output paths for local C++ builds (#49575)
## Summary of the Pull Request

Fixes two local C++ build reliability problems:

- Compiles all PowerToys C++ projects as UTF-8 through
`Cpp.Build.props`, so builds do not depend on the active Windows code
page. On code page 936, UTF-8 punctuation in BOM-less source files
otherwise triggers C4819 and fails the build because warnings are
treated as errors.
- Uses `$(RepoRoot)` for Keyboard Manager repository paths and
standardizes native/test output directories. This makes direct project
builds find the resource conversion script and headers, places the
Editor wrapper beside the WinUI app, and keeps the Engine test DLL under
the repository test output directory.

No runtime logic, end-user strings, dependencies, or binaries are added.

## PR Checklist

- [x] Closes: #49573
- [x] Closes: #49574
- [x] **Communication:** Discussed the shared UTF-8 policy with a
PowerToys collaborator in this PR
- [x] **Tests:** Existing Keyboard Manager Engine tests pass; no new
tests are needed for project-only changes
- [x] **Localization:** No end-user-facing strings are changed
- [x] **Dev docs:** No documentation changes are required for project
configuration fixes
- [x] **New binaries:** No new binaries are added
- [x] **Documentation updated:** No user documentation changes are
required

## Detailed Description of the Pull Request / Additional comments

`Directory.Build.props` imports `Cpp.Build.props` for C++ projects.
Defining `/utf-8 %(AdditionalOptions)` in its shared `ClCompile`
settings makes source decoding deterministic across the native codebase
and prevents future BOM-less UTF-8 source files from reintroducing the
same locale-dependent failure. `/utf-8` explicitly sets both the source
and execution character sets instead of suppressing C4819 or replacing
valid Unicode text.

`$(SolutionDir)` is only reliable when MSBuild is invoked through a
solution. The repository's local build script builds `.vcxproj` files
directly from their project directories, where `$(RepoRoot)` is the
stable repository root property. The wrapper output now follows the
existing `$(RepoRoot)$(Platform)\$(Configuration)\WinUI3Apps\` pattern
used by other native WinUI dependencies.

## Validation Steps Performed

All successful builds used the repository build scripts with `-Platform
x64 -Configuration Debug`.

- Ran `tools/build/build-essentials.cmd`: solution restore, Runner, and
Settings all succeeded with empty errors logs.
- Built `FancyZonesLib` successfully after it had failed with a
resource-related CL exit during a full parallel build.
- Built `WorkspacesModuleInterface` successfully, validating that
existing UTF-16 BOM headers remain compatible with the shared option.
- Built `ZoomItBreak` and `ZoomIt` successfully.
- Built `KeyboardManagerEngineTest` successfully.
- Built `KeyboardManagerEditor` and `KeyboardManagerEditorUI`
successfully after the documented essentials prerequisite.
- Confirmed the successful native build logs contain `/utf-8` compiler
invocations and all corresponding `build.debug.x64.errors.log` files are
empty.
- Ran `vstest.console.exe` against the Keyboard Manager Engine test
assembly: 103/103 passed.
- Confirmed `PowerToys.KeyboardManagerEditorLibraryWrapper.dll` is
emitted to `x64/Debug/WinUI3Apps`.
- Confirmed `KeyboardManager.Engine.UnitTests.dll` is emitted to
`x64/Debug/tests/KeyboardManagerEngine`.
- Previously manually verified the x64 Debug PowerToys build can open
Keyboard Manager Editor without 0x8007007E.

A full `PowerToys.slnx` x64 Debug build was attempted twice. The first
attempt exhausted the remaining 62 MB of disk space. After clearing
52.46 GB of ignored build outputs, the second attempt still exceeded the
machine's temporary disk/commit limits (`CL.exe` exit `0xC000012D` and
an out-of-space cppwinrt write). Before that resource failure, the log
contained 4,642 `/utf-8` command entries and no character-set
diagnostics. The full configuration matrix is left to PR CI rather than
bypassing normal build settings locally.

6bb16d014b [Settings][Image Resizer] Edit/add presets in a ContentDialog instead of a Flyout (#49161)
## Summary of the Pull Request

Replaces the inline preset-edit **Flyout** on the Image Resizer settings
page with a **ContentDialog**, matching the add/edit pattern already
used on the **Color Picker** page. This aligns the experience with the
Windows 11 / Fluent paradigm and fixes preset settings being saved on
every intermediate change.

Editing now happens on a **working copy** of the preset
(`ImageSize.Clone()`), which is committed only when the user presses
**Save/Update**. As a side effect, the intermediate width/height spinner
changes no longer persist `settings.json` / `sizes.json` on every value
change — resolving #36938.

The per-row **delete** action moves from an inline trash button into a
**"..." (More options)** `MenuFlyout`, again matching the Color Picker
page.

Historically this editing was a Flyout rather than a ContentDialog due
to known `ContentDialog` / `XamlRoot` issues back when Settings was a
UWP app. Now that Settings is on WinUI 3 / Windows App SDK,
`ContentDialog` works reliably (as Color Picker's `ColorFormatDialog`
demonstrates), so the original constraint no longer applies.

- [ ] **Dev docs:** Added/updated

## Detailed Description of the Pull Request / Additional comments

- **Dialog:** Clicking a preset card (or **Add new size**) opens an
`EditSizeDialog` `ContentDialog`. Fields are bound with compiled
`{x:Bind}` against a working-copy `EditingSize`. The dimensions field
header is dynamic — **"Width"** when height is used, **"Size"** for
aspect-ratio-preserving percentage scaling — so the label isn't
misleading. The dialog is widened for a less cramped layout.
- **Save semantics:**
  - `ImageSize.Clone()` — builds the editable working copy.
- `ImageResizerViewModel.CreateNewImageSizeModel()` — builds a
default-valued model for the add dialog without adding it to `Sizes`.
- `ImageResizerViewModel.AddImageSize(ImageSize)` — commits a new preset
with the next unique ID.
- `ImageResizerViewModel.UpdateImageSize(original, updated)` — applies
edited values back onto the original, temporarily detaching the per-item
`PropertyChanged` save handler so it persists **once** instead of on
every property. This is what fixes the "saved too often" behavior in
#36938.
- **Delete:** per-row `Button` → `MenuFlyout` with a Delete
`MenuFlyoutItem`; the `ImageSize` is passed via
`CommandParameter="{x:Bind}"` (robust inside a flyout popup) and the
Yes/No confirmation dialog is preserved.

## Validation Steps Performed

- Built `PowerToys.Settings` (x64/Debug) — clean (exit 0).
- Ran the runner from this build and manually validated in Settings →
Image Resizer:
- **Add new size** opens the dialog pre-filled; Save adds the preset;
Cancel discards.
- **Editing** a preset in the dialog and pressing Cancel leaves the
original untouched (working-copy clone).
- Selecting **Percent** shows the **Size** header (not a misleading
"Width").
- Spinning width/height inside the dialog no longer writes settings
files on each change; a single save occurs on Update (#36938).
- The **"..."** menu shows **Delete**, with the confirmation dialog
intact.

d04ebff5e7 CmdPal: Use RepoRoot instead of SolutionDir (#49643)
As it turns out, the robots are unbelievably stupid. When they build our
projects to verify their changes, they will often just build the .csproj
that they changed rather than building it in the context of the
solution. On the surface, this feels like a good idea. Only build the
thing that changed.

However, because they're not building it in the context of a solution,
the MSBuild variable `$(SolutionDir)` doesn't get expanded to the actual
directory of the solution. Instead, it just gets treated as the *path to
the project*. This creates terrible recursive loops where the output of
a project gets dumped relative to the project itself, and then that gets
taken as input to the project's package outputs, and eventually you're
gonna end up with a max path overrun.

The very easy solution here is to just replace `$(SolutionDir)` with
`$(RepoRoot)`.

If we use that variable, then the dumb robots will still get the correct
value for that variable when they build just a project. And for all the
actual humans, everything will work exactly as it did before.

10236ee8c7 [Quick Accent] Fix the accent bar's blank first frame and its under-measured width (#49633)
## Summary of the Pull Request

Two defects in the WinUI 3 Quick Accent selector. They look unrelated
but share a root: the overlay owns no layout of its own, so `MainWindow`
sizes and shows it by hand — and both halves of that hand-rolled logic
rest on an assumption that does not hold.

* **#49489** — the bar appears blank, too wide and clipped on the right
for a few frames, then snaps into place. A hidden WinUI 3 window renders
nothing, so `ShowWindow(SW_SHOWNA)` puts the HWND on screen before the
freshly rebuilt accent list has ever been laid out.
* **#49488** — the window is sized narrower than its own content
whenever a glyph is wider than the 48 DIP cell, so the list silently
scrolls inside it and the trailing accents are pushed against the right
edge.

test result:

## Detailed Description of the Pull Request / Additional comments

### #49489 — the blank, over-wide, clipped first frame

The window is never actually repositioned or resized. Measuring the two
frames in the issue shows the same HWND rect in both: identical left
edge, and the bad frame's hard right cut sits exactly where the good
frame's rounded corner plus its 24 DIP margin ends. What changes is the
**content** — it is composed once from a stale layout, then re-laid-out.

Two ordering problems produced that stale composition:

1. `TransientSurface` is `Collapsed` while hidden and is only flipped to
`Visible` from the `Showing` event, which `TransparentWindow.RaiseShow`
raises **after** `ShowWindow(SW_SHOWNA)`. The accent bar's subtree
therefore provably has not been measured or arranged at the moment the
HWND becomes visible.
2. The hide path called `ViewModel.Characters.Clear()` synchronously
right after `Hide()` — but `Hide()` only *queues* the dismissal, so the
still-visible window rendered an empty bar at the old width. That empty
card is exactly what the next summon put back on screen.

The fix mirrors what the WPF implementation did for the same symptom in
#46593 (render off screen, then `SetWindowPos` into view), adapted to
WinUI 3 where a hidden window does not render at all:

* Show the bar with `Selector.Opacity = 0`, lay it out, and unveil it
once `CompositionTarget.Rendering` confirms a couple of frames have
elapsed. `Opacity = 0` still renders (unlike `Visibility.Collapsed`),
which is exactly what is needed here. A 150 ms timeout backs it up — not
because frames stop arriving (attaching a `Rendering` handler forces the
UI thread to run every frame) but because the tick cadence carries no
guarantee and can stop for a locked or fully occluded session; on that
path the bar simply appears the way it used to, so it can never get
stuck invisible.
* Size the bar **twice** per summon: once before `Show`, and again after
the first real layout pass. The first measurement runs while the surface
is still `Collapsed` and, on the first summon of the process, before its
template has ever been applied, so it can report less than the items
need. The correction happens while the bar is still transparent, so it
is never seen as a resize.
* Leave the characters in the list on hide. The next summon clears and
refills them anyway, and not clearing them removes the blank-bar frame
at the source.
* A generation counter drops a pending reveal when the summon is
dismissed or superseded before its frame lands, and arming a new summon
detaches the previous one's per-frame handler so it cannot unveil the
new bar ahead of its own layout pass.

### #49488 — width derived from the item count instead of measured

`MainWindow` computed the window width as `Characters.Count * 48`, while
the XAML cell is `MinWidth="48"` — a *minimum*, not a fixed width.
`ListViewItem` → `Grid MinWidth=48` with a `ContentPresenter Margin=12`,
so a cell is `max(48, glyphWidth + 24)`: any glyph wider than 24 DIP (₹,
‰, ﷼, ៛, CJK fallbacks) grows its cell. With **All languages** selected,
R and P each carry ~20 characters and the accumulated error is enough
for the real content to overflow the window. The ListView's
`ScrollViewer` (`HorizontalScrollMode="Enabled"`,
`HorizontalScrollBarVisibility="Hidden"`) then absorbs the overflow
invisibly, and `ScrollIntoView` starts scrolling a bar that should not
scroll at all.

The pre-migration WPF window used `SizeToContent="WidthAndHeight"` and
only set `MaxWidth`, so the layout system measured the same item
template and the window simply grew — which is why this never showed up
before. `AppWindow` has no `SizeToContent` equivalent, and the migration
replaced it with a constant model.

Now:

* `SelectorControl.MeasureContentWidthDip()` measures the list against
an unbounded width and returns what the items actually need. Measuring
explicitly, rather than reading a stale `DesiredSize`, addresses the
concern recorded in the original comment: the bar is rebuilt on every
summon while the window is still hidden, so no layout pass has run for
the new items yet.
* `Calculation.GetToolbarWidth()` — a pure function, hence the unit
tests — floors that measurement at `itemCount * minItemWidth` (every
cell is at least the minimum, so a list that could not be measured
reports 0 and safely falls back to the old estimate instead of
collapsing the bar), applies the description row's minimum width, and
clamps to the display's usable width so long character sets still scroll
on purpose.
* The clamp's lower bound is `minItemWidth + chromeWidth` — one cell
plus the space around it, the narrowest bar that can still draw a glyph
— and its upper bound is `Math.Max(minItemWidth + chromeWidth,
maxWidth)`, because a display narrower than that floor would otherwise
invert the bounds and make `Math.Clamp` throw.

`DescriptionMinWidthDip = 648` masked this bug whenever the Unicode
description row was on and the character set short, which is likely why
#49402 (description-row width) did not surface it.

## Validation Steps Performed

* `PowerAccent.Core`, `PowerAccent.UI` and `PowerAccent.Core.UnitTests`
build clean (Debug|x64).
* `PowerAccent.Core.UnitTests`: 32/32 pass, including the 11
`GetToolbarWidth` cases — narrow glyphs hug the item count, wide glyphs
win over the count estimate (the #49488 regression guard), the
measurement winning by a single DIP, a partly realized list keeping the
item-count floor, an unmeasured list falling back to the estimate,
over-long content clamping to the display maximum, the description row
widening a short bar but not a long one, the description minimum losing
to a narrower display, and both ends of the clamp. The lower clamp bound
was verified by mutation: rewriting it to `Math.Clamp(width, 0, ...)`
fails only `GetToolbarWidth_EmptyList_FallsBackToOneCellPlusChrome`.

e542b82a2a [PowerAccent] Forward key-up after false activation (#49644)
## Summary of the Pull Request

Quick Accent passes the owner letter's key-down to the rest of the
low-level keyboard hook chain. When activation is canceled before the
configured threshold, trigger-key modes currently swallow the matching
key-up. This leaves downstream keyboard state reporting the letter as
held and causes Keyboard Manager's shortcut-to-shortcut safety check to
reject later remaps.

This change forwards the owner letter's key-up on that false-start path,
balancing the event pair for downstream hooks and applications.
Successful Quick Accent activation behavior is unchanged.

Partial fix: #38089

## PR Checklist

- [ ] Closes 
- [ ] **Communication:** Root cause, deterministic reproduction, and
validation were posted on #38089; awaiting core-contributor review
- [ ] **Tests:** No automated low-level keyboard-hook test seam is
available; extensive manual validation is documented below

- [x] **New binaries:** No new binaries were added
- [ ] **Documentation updated:** No user-facing documentation change is

## Detailed Description of the Pull Request / Additional comments

The false-start path runs when the owner letter is released before Quick
Accent's activation threshold. Its key-down was already allowed through
by `OnKeyDown`, but `OnKeyUp` returned `true` for the Space/arrow
activation modes. Returning `true` from the low-level hook prevents
later hooks and the target application from receiving the release.

Keyboard Manager intentionally checks that no unrelated key is held
before applying a shortcut-to-shortcut remap. The missing release
therefore makes several remaps stop together while both PowerToys
processes remain responsive. It also explains why locking and unlocking
the Windows session restores them: the stale keyboard state is reset.

The fix is intentionally in Quick Accent rather than relaxing Keyboard
Manager's safety check, which must continue to reject remaps when
unrelated keys are genuinely held.

## Validation Steps Performed

- Built `PowerAccentKeyboardService` from current `main` in Release x64:
0 warnings, 0 errors. Spectre mitigation was disabled for the local
build because the corresponding Visual Studio libraries were not
installed.
- Built and installed the same change against PowerToys 0.100.2 so the
test DLL matched the installed release ABI.
- Repeated dozens of false activations with E/N/O/Y by pressing Space
and releasing the owner letter before the 500 ms threshold.
- Interleaved successful Quick Accent selections to verify normal
activation still worked.
- Captured `GetAsyncKeyState` transitions and confirmed both the letter
and Space changed from down to up; all sampled keys remained up after
testing.
- Continuously tested a Left Shift+O -> Left Alt+Tab Keyboard Manager
remap; it remained functional throughout.
- Completed an additional user soak test without recurrence;
locking/unlocking was no longer required.

97aeab4e96 [Shortcut Guide] Add support for Greenshot (#49407)
## Summary of the Pull Request

Adds a Shortcut Guide manifest for **Greenshot**.

- **New manifest:**
`src/modules/ShortcutGuide/ShortcutGuide.Ui/Assets/ShortcutGuide/Manifests/Greenshot.Greenshot.en-US.yml`:
32 shortcuts for `Greenshot.exe`, grouped into five sections:
* **Capture:** Capture region, Capture last region, Capture window,
Capture fullscreen, Capture Internet Explorer tab
* **While selecting a region:** switch region/window mode, select a
child window element, toggle magnifier, confirm selection, cancel
capture
* **Editor - draw:**
rectangle/ellipse/line/arrow/freehand/highlight/obfuscate/crop/text/selection
tools, enlarge screenshot, crop to visible elements, paste image from
clipboard
* **Editor - text:** insert line break, delete previous word, select all
text, finish editing
* **Editor - export:** save, save as, copy image to clipboard, print,
e-mail
- **No code changes.** The manifest is auto-included via the existing
`Manifests/*.yml` glob in `ShortcutGuide.Ui.csproj`.
- `BackgroundProcess: true`, matching the bundled PowerToys-itself
manifest, since Greenshot's core value is its global capture hotkeys,
which work regardless of the currently focused window.
- Introduces a `<PrtScn>` token for the Print Screen key (not previously
needed by any bundled manifest, since Greenshot's capture shortcuts are
all built around it) alongside the existing `<Space>`, `<Enter>`,
`<Esc>`, `<Backspace>`, `<PageDown>` named-key tokens.

## PR Checklist

- [ ] **Closes:** #ISSUE_NUMBER
- [ ] **Communication:** discussed in the linked issue
- [ ] **Tests:** N/A for data; relies on the existing manifest
deserialization path
- [x] **Localization:** all end-user-facing strings can be localized
- [ ] **Dev docs:** N/A, no schema changes
- [ ] **New binaries:** N/A
- [ ] **Documentation updated:** N/A
- [x] **Local run:** see issue screenshot

## Detailed Description of the Pull Request / Additional comments

The Shortcut Guide displays per-app shortcuts from YAML manifests,
matched to the foreground window (or shown continuously for background
processes) via `WindowFilter`/`BackgroundProcess`. Adding support for an
app is purely additive: drop a `<PackageName>.<locale>.yml` file in the
`Manifests` folder and it's picked up by the existing build glob and
index generator.

- `PackageName: Greenshot.Greenshot` is the WinGet package identifier;
`WindowFilter: "Greenshot.exe"` is the process name (confirmed against a
signed 1.3.315 build).
- `Name: Greenshot` is the display name shown in the Shortcut Guide app
picker.
- Shortcut names follow the repo's sentence-case convention (capitalize
only the first word plus proper nouns/product names).
- Five shortcuts are marked `Recommended`: Capture region, Capture last
region, Capture window, Save, Copy image to clipboard — the capture and
export actions used most often.
- Shortcut source: Greenshot's official help page
(https://getgreenshot.org/help/), cross-checked against the unofficial
`defkey.com` reference.

## Validation Steps Performed

- **Source fidelity:** every shortcut and modifier combination matches
the official Greenshot help page one-to-one; no unofficial-source
shortcuts were added without confirming them against the official page.

1980ca5ece [Runner][Interop] Authenticate Settings/Quick Access named-pipe clients before dispatch (CWE-732/CWE-862) (#49527)
## Summary of the Pull Request

The Runner is the **server** for the two-way named pipes it uses to talk
to `PowerToys.Settings.exe` and the Quick Access host, and it dispatched
privileged JSON commands (`killrunner`, `restart_elevation`,
`module_status`, `powertoys`, `language`, ...) **without authenticating
the caller**. When PowerToys runs elevated ("Run as administrator"), the
pipe DACL grants the shared **Logon SID**, so **any same-user Medium-IL
process could connect and inject commands** — a local privilege
escalation (CWE-732 / CWE-862). The pipe DACL cannot distinguish the
legitimate Medium-IL Settings child from a same-user attacker (identical
user SID, integrity level, and logon session), so this PR authenticates
the connecting process's **binary identity** before any dispatch.

## PR Checklist

- [x] **Tests:** Added/updated and all pass (native gate tests + C#
regression)
- [x] **Localization:** No new end-user-facing strings (only a
diagnostic runner log line)
- [x] **New binaries:** None — the new code compiles into the existing
`PowerToys.Interop` and `runner` binaries; tests were added to the
existing `Common.Utils.UnitTests` project

## Detailed Description of the Pull Request / Additional comments

New `src/common/interop/pipe_caller_auth.{h,cpp}` adds
`interop_auth::AuthenticateClient`, invoked from
`TwoWayPipeMessageIPC::handle_pipe_connection` **before** a message is
queued (fail-closed). A connecting client is accepted only if it is:

- under the **Runner-relative install directory**
(`get_module_folderpath()\WinUI3Apps`, so it adapts to installed and
dev-build layouts),
- an **allow-listed basename** (`PowerToys.Settings.exe` /
`PowerToys.QuickAccess.exe`),
- the Runner's **exact file version** (anti-downgrade), and
- **Microsoft Authenticode-signed**.

The signature is anchored to the **LOCAL MACHINE root store**
(`HCCE_LOCAL_MACHINE` +
`CertVerifyCertificateChainPolicy(AUTHENTICODE)`) rather than
`WinVerifyTrust`'s default user+machine union: the Runner runs as the
same user as a potential attacker and would otherwise trust a forged
signer added to `CurrentUser\Root`. Verdicts are cached per `(pid,
process-creation-time, policy)` with a short TTL so the check isn't
re-run on every message (each `send` opens a new connection). Rejections
are logged.

The gate is added via an **additive** `start(HANDLE, CallerPolicy)`
overload; the managed `start(nullptr)` path is unchanged (gate
disabled), so there is **no ABI break** to `PowerToys.Interop`.
`PIPE_REJECT_REMOTE_CLIENTS` is also set. In **Debug** builds only the
signature check is relaxed (directory/basename/version stay enforced) so
local unsigned builds still connect; the relaxation is compiled out of
Release.

**Scope:** this PR covers the two elevated Runner-server pipes (Settings
+ Quick Access), which are the actual EoP surface. The reverse
Runner->Settings response direction, the duplicated Workspaces
transport, and the AdvancedPaste/PowerDisplay module pipes are
intentionally out of scope and can be handled as follow-ups.

## Validation Steps Performed

**Automated**
- **Native unit tests** (`Common.Utils.UnitTests`,
`PipeCallerAuthTests`): legitimate self-caller accepted; wrong
basename/directory rejected with the reject-log callback firing; version
reading. 6/6 pass.
- **C# regression** (`Microsoft.Interop.Tests.TestSend`): managed
gate-disabled round-trip still works.
- **Builds:** runner Debug + Release, `PowerToys.Interop` Debug +
Release, and the test project all build/link clean.

**Official signed build (validates the Release-only signature path that
local Debug builds skip)**
- Queued the internal "PowerToys Signed YAML Release Build" for this
branch — **green** (`result: succeeded`). The produced installers are
Authenticode `Valid`, signer `Microsoft Corporation`.

**Manual testing on the signed installer (elevated Runner) — passed**
- Installed the signed build and ran the Runner **as administrator**.
Settings and Quick Access open and are fully functional; settings apply,
module toggles work, and the hotkey-conflict request/response
round-trips.
- **No** `Rejected unauthenticated ...` lines during legitimate use →
the genuine signed `PowerToys.Settings.exe` is accepted by the
machine-root signature + version + directory checks (verified in
`RunnerLogs\runner-log_*.log`, requests dispatched normally).
- **Security (negative) check:** a non-elevated `powershell.exe`
discovered the runner pipe via the pipe namespace and attempted
`{"killrunner":true}`; the write failed ("Pipe is broken") because the
Runner rejected the caller and disconnected before dispatch.
`PowerToys.exe` stayed running and logged: `Rejected unauthenticated
Settings pipe client: pid=... image='...\powershell.exe'
reason=bad-directory`.

ba2e89c428 PowerDisplay: Fall back to persisted VCP values when a monitor read fails (#49445)
## Summary of the Pull Request

On a monitor whose DDC/CI engine answers intermittently, every discovery
pass starts from nothing. A panel that reported its brightness a minute
ago can lose that control — or drop out of the flyout entirely — because
one pass happened to fail.

This persists every range-valid VCP value read off a monitor, keyed by
its canonical DevicePath. In Maximum compatibility mode a later
discovery falls back to that value when the hardware will not answer.

Scope is intermittent failure, not permanent failure: the cache can only
replay a value the hardware answered at least once, so a panel that
never reads a code successfully sees no change. This partially addresses
#49342.

## PR Checklist

- [x] Closes: #49342
- [ ] **Communication:** I've discussed this with core contributors
already. If the work hasn't been agreed, this work might be rejected
- [x] **Tests:** Added/updated and all pass

this PR adds none
- [ ] **Dev docs:** Added/updated
- [x] **New binaries:** Added on the required places — none added, so no
signing JSON, installer WXS or CI YML change is required
- [ ] **Documentation updated**

## Detailed Description of the Pull Request / Additional comments

### What is stored

`MonitorStateManager` implements `IKnownGoodVcpStore`, so the cache
rides in the existing `monitor_state.json` next to the user's saved
brightness rather than in a new file. Each entry is a
`KnownGoodVcpFeature`: code, current, maximum, and when it was last
read.

Only range-valid observations are stored, so the common `current=0 /
max=0` garbage reply never enters — it fails `VcpFeatureValue.IsValid`.

Writes are not gated on Maximum compatibility mode, only reads are. A
monitor that reads cleanly today can start failing after a cable or dock
change, and a lazily populated cache would be empty on exactly the first
pass that needs it.

### How a cached value is used

`VcpDiscoveryEvidence.Reconcile` gains the cache as a third source
alongside the parsed capabilities string and this pass's probe:

| this pass | cache | result |
| --- | --- | --- |
| read succeeded | — | live value wins, cache refreshed |
| replied, range unusable | hit | cached value applied,
`MonitorReadFlags` left clear |
| no reply | hit | cached value applied, `MonitorReadFlags` left clear |
| code never probed (caps parsed) | hit | value applied only after one
live read is attempted |

The last row matters: on the caps-parsed path nothing has confirmed the
cached value this pass, so the hardware is asked first. On the probe
path it has already been asked, and re-reading would be pure I2C noise.

`MonitorReadFlags` stays clear for anything the hardware did not answer,
so a cached value never masquerades as an observation — which #49577
depends on, since it made the restore path write whenever the flag is
unset. One consequence is worth naming: the flyout draws a slider at the
cached position while `powerdisplay get` reports that setting as
unknown, because `MonitorDtoProjector` gates on `supported && read`.

### Keeping the cache current

`RefreshKnownGoodAfterWrite` restamps an entry after a successful
`SetVCPFeature`, so a slider move cannot leave the cache holding the
pre-write value. It refreshes only an entry a real read established, and
only when the value was scaled against the maximum that entry holds — a
monitor whose discovery read failed still carries a placeholder max, and
writing that back would mis-scale every later write.

`RemoveKnownGoodFeatures` clears the cache for monitors a settings
reconciliation observably dropped, leaving the user's saved values
alone. Cleanup is driven by an observed drop, never by absence from the
rebuilt list: a missing or corrupt `settings.json` yields a defaults
object indistinguishable from a real one, and pruning by absence would
wipe every monitor not connected at that instant.

A re-observation that changes nothing refreshes the in-memory timestamp
but does not mark the file dirty, so a discovery pass no longer rewrites
`monitor_state.json` for a moved timestamp alone.

## Validation Steps Performed

- `PowerDisplay.Lib`, `PowerDisplay.Lib.UnitTests` and `PowerDisplay`
built for x64 Debug with VS MSBuild — 0 errors, 0 warnings;
`PowerDisplay.Lib.UnitTests.dll` under `vstest.console.exe`: **301
passed, 0 failed**
- **Affected-hardware validation on the AOC Q27G3XMN is still pending.**
That monitor, or an equivalent controllable DDC/CI setup, was not
available locally. The paths this PR changes are reachable only on
hardware whose capabilities string is unusable or whose VCP reads fail
intermittently, so this is the main outstanding risk.

37d8729ac3 FancyZones: apply edited custom layout spacing/sensitivity/zone count to active work areas immediately (#49433)
## Summary of the Pull Request

When a **custom layout** is edited in the FancyZones editor while
windows are already snapped to it, changes to the layout's *scalar*
properties — **spacing between zones**, **highlight/activation
sensitivity radius**, and **zone count** (for canvas layouts) — were
**not applied to already-active work areas** until PowerToys (or
FancyZones) was restarted. Only the grid **shape/edges** refreshed live.

This PR makes those scalar edits take effect immediately on existing
work areas, resolving the remaining gap in issue 44058.

## PR Checklist

- [x] Closes: #44058
- [x] **Communication:** This addresses the behavior tracked in the
linked issue.
- [x] **Tests:** Added
`EditedCustomLayoutSpacingRefreshesExistingWorkArea` regression test;
existing FancyZones unit tests pass.
- [x] **Localization:** No new end-user-facing strings.
- [x] **Dev docs:** N/A (no public API or doc surface change).
- [x] **New binaries:** None added.

## Detailed Description of the Pull Request / Additional comments

### Root cause

For a **Custom**-type layout, `WorkArea::CalculateZoneSet` builds its
`Layout` from `AppliedLayouts::GetDeviceLayout()`, which returns a
snapshot from `applied-layouts.json`. The zone **shape** is read live
from the `CustomLayouts` store, but the scalar properties (`spacing`,
`sensitivityRadius`, and `zoneCount`) were taken from that **stale
applied-layouts snapshot**. So when the editor updated the custom layout
and fired `WM_PRIV_CUSTOM_LAYOUTS_FILE_UPDATE`, the existing work areas
re-laid-out their grid geometry but kept the *old*
spacing/sensitivity/zone count.

### The fix

In `WorkArea::CalculateZoneSet`, for Custom-type layouts, re-derive the
scalar properties from the **live** `CustomLayouts` store instead of the
stale snapshot:

```cpp
if (const auto refreshed = CustomLayouts::instance().GetLayout(appliedLayout->uuid))
{
    appliedLayout = refreshed;
}
```

`CustomLayouts::GetLayout` returns the canonical `LayoutData` used by
the apply path (it derives grid zone count from `zoneCount()` and canvas
zone count from `zones.size()`), so the refreshed values exactly match
what a fresh apply would produce.

**Why this is low-risk:**
- Scoped strictly to **Custom** layouts; templated layouts
(Grid/Columns/etc.) are untouched.
- At initial apply-time, the live store and the applied-layouts snapshot
are equal, so behavior is unchanged for the common case — only a genuine
*edit* of an already-applied custom layout changes the outcome (which is
the intended fix).

This complements the editor-side `RefreshLayouts()` call (which
refreshes zone shape) so that **all** properties of an edited custom
layout now apply live.

## Validation Steps Performed

**Automated:** Added
`EditedCustomLayoutSpacingRefreshesExistingWorkArea` in
`FancyZonesTests/UnitTests/WorkArea.Spec.cpp`. It creates a work area on
a grid custom layout, asserts adjacent zones are flush, then edits the
custom layout's spacing, re-initializes the layout via `InitLayout()`,
and asserts the new spacing gap is present on the existing zones. Built
the FancyZones unit tests and ran the `WorkArea` suite — all pass.

**Manual (end-to-end):**
1. Create a **grid custom layout** in the FancyZones editor and apply
it.
2. Snap a window into one of its zones.
3. Re-open the editor, edit the layout: change the **edge position**
*and* the **space between zones** (and optionally sensitivity), then
**Save**.
4. **Before this fix:** the zone edges move, but the spacing between
snapped windows keeps the *old* gap until PowerToys is restarted.
5. **After this fix:** the new spacing (and sensitivity) are applied to
the already-snapped/active work area immediately, with no restart.

f4b3dcde03 PowerDisplay: Funnel both monitor-state saves through one locked write (#49629)
## Summary of the Pull Request

`MonitorStateManager` wrote `monitor_state.json` from two independent
paths: the debounced save used `File.WriteAllTextAsync`, `Dispose` used
`File.WriteAllText`. Both open the path with `FileShare.Read`, so
disposing while a debounced save had already passed its delay left the
two racing for the same handle — the loser was denied at `CreateFile`
and its payload was dropped whole, into a catch that only logged.

Both paths now go through one method that serializes and writes under a
single lock, and the file is published by rename instead of being
written in place.

### The collision

`Dispose` disposes the debouncer before flushing, which cancels a
pending `Task.Delay` but cannot reach a save that has already passed it
and stopped observing the token. That save is inside
`File.WriteAllTextAsync` when `Dispose` reaches its own
`File.WriteAllText`. Both open with `FileMode.Create, FileAccess.Write,
FileShare.Read`, and Windows checks sharing in both directions, so the
second open fails with `ERROR_SHARING_VIOLATION`. The loser never gets a
handle and writes zero bytes — a torn or interleaved file was never
reachable, only a dropped write.

### Why the flush could actually be lost

A bare collision costs only a redundant write: both paths serialize the
same live `_states`, and `UpdateMonitorParameter` mutates it
synchronously before arming the debounce, so whichever writer wins
already has the user's latest value.

The case that loses data is narrower. The debounced save built its JSON
*before* the `await`, so:

1. the debounced save snapshots `{brightness: 60}` and opens the file;
2. the user moves a slider to 70 — `_states` is updated, a new debounce
is armed;
3. the user quits; `Dispose` snapshots `{brightness: 70}` and is denied
at `CreateFile`;
4. the async write completes, publishing 60.

70 is gone. The window is the few hundred microseconds the async write
holds the handle, but it is exactly the window in which the user is
quitting.

### The fix

Both paths call `WriteStateFile`, which takes `_writeLock` and does the
serialize-and-write inside it. `BuildStateJson` runs under the lock too,
so the last snapshot built is the one that lands — a writer that queues
behind another re-snapshots rather than replaying a stale payload.

The write is synchronous on both paths. `Dispose` has to flush without
awaiting, the file is a few hundred bytes, and the async API was the
only reason there were two write paths to collide in the first place.
That is also why the guard is a plain `lock` rather than a
`SemaphoreSlim`: with neither caller async there is no
blocking-on-an-async-method concern left to design around.

`Dispose` keeps its ordering — dispose the debouncer so nothing new is
scheduled, then flush if the state was dirty.

### Publishing by rename

The bytes go to a temp file and are renamed in, matching
`CrashDetectionScope` and `ProfileStore` in the same module. An in-place
write truncates at `CreateFile` before it writes anything, and two exit
paths never reach `Dispose` at all — `App.OnLaunched` registers
`TerminatePowerDisplayEvent` and the runner-exit watchdog, and both call
`Environment.Exit(0)` outright. An interrupted write there would leave a
zero-byte file, which `LoadStateFromDisk`'s catch turns into "no saved
state for *any* monitor" — total loss rather than the last change.

There is deliberately no `Flush(flushToDisk: true)` to go with it. The
threat here is process death, which the page cache survives, not power
loss; and this flush runs on the UI thread at shutdown, where a
`FlushFileBuffers` on a busy disk is the one change in this area a user
could actually feel.

### The dirty flag

`SaveStateToDisk` cleared `_isDirty` *after* the write. A change landing
between the snapshot and that assignment set the bit and had it
immediately cleared; `Dispose` then read `wasDirty == false`, cancelled
the debounce that change had scheduled, and skipped the flush — losing
exactly the last change this path exists to preserve. It is now cleared
before the snapshot and re-marked if the write throws, so a change that
lands mid-write either rides along in the snapshot or stays dirty.

### Testability

`MonitorStateManager` gains an internal constructor taking a state file
path, so tests can drive it against a temp directory instead of the real
LocalAppData location.

## Validation Steps Performed

- `PowerDisplay.Lib` and `PowerDisplay.Lib.UnitTests` built for x64
Debug with VS MSBuild; `PowerDisplay.Lib.UnitTests.dll` under
`vstest.console.exe`: **273 passed, 0 failed** (4 of them in
`MonitorStateSaveTests`)
- Removing `lock (_writeLock)` fails
`ConcurrentWrites_DoNotCollideOnTheStateFile` with the same "used by
another process" `IOException` the collision produces, so the test pins
the guard rather than the shape of the code
- `FailedWrite_LeavesTheExistingStateFileIntact` occupies the temp path
with a directory so the write fails at exactly the point an in-place
`File.WriteAllText` would already have truncated the published file;
against the previous in-place write the same test fails, since that
write would succeed and replace the file
- No end-to-end manual check was performed. The window is a few hundred
microseconds wide and only opens when a debounced save is mid-write at
the exact moment `Dispose` runs, so reproducing it by hand is unreliable
— the concurrency test drives the same contention deterministically
instead

### Known gap, not addressed here

`TerminatePowerDisplayEvent` and the runner-exit watchdog call
`Environment.Exit(0)` without ever running `Dispose`, so on those paths
up to a full `SaveDebounceMs` (2 s) of changes is dropped
unconditionally — no race required. That is a larger loss surface than
the one this PR closes, and the module already has the machinery to fix
it (`CrashDetectionScope` subscribes to `AppDomain.ProcessExit` through
an `IProcessExitHook` seam for precisely these paths). Left out to keep
this PR to one logical change; happy to open a follow-up issue.

d2c53bf386 [ZoomIt] Add DemoMirror feature (#49607)
Mirror the screen, a selected region (Shift), or the window under the
cursor (Alt) onto a second monitor - including the mouse pointer - so a
demo can be shown on a presentation display without leaving the current
view. Adds the native MirrorWindow implementation, a DemoMirror options
tab (Ctrl+9 default, plus Track window region), and the corresponding
Settings UI (ZoomIt page group, view model, properties, and resources).

## Summary of the Pull Request

Adds a **DemoMirror** feature to ZoomIt. It mirrors the screen, a
selected region (Shift), or the window under the cursor (Alt) onto a
second monitor — including the mouse pointer — so a demo can be shown on
a presentation display without leaving the current view.

This introduces the native `MirrorWindow` implementation, a new
DemoMirror options tab (default hotkey **Ctrl+9**, plus a **Track window
region** option), and the corresponding Settings UI wiring (ZoomIt page
group, view model, properties, and localized resources).

## Detailed Description of the Pull Request / Additional comments

DemoMirror lets a presenter keep working on their primary display while
a second monitor shows a live mirror of a chosen source. Three capture
modes are supported via the DemoMirror hotkey (default **Ctrl+9**):

- **Full screen** — `Ctrl+9`: mirrors the entire source screen.
- **Region** — `Ctrl+Shift+9`: mirrors a user-selected rectangular
region.
- **Window** — `Ctrl+Alt+9`: mirrors the window currently under the
cursor. With the **Track window region** option enabled, the mirror
follows the window as it moves/resizes.

The mirror includes the mouse pointer so pointer movement and clicks are
visible on the presentation display.

**Native (C++ / `PowerToys.ZoomIt.exe`)**
- New `MirrorWindow.cpp` / `MirrorWindow.h` implementing the mirror
capture/render window. Mirror windows use `WS_EX_NOACTIVATE |
WS_EX_TRANSPARENT` so they never steal focus from the source.
- `Zoomit.cpp`: registers the DemoMirror hotkeys and wires the
start/stop handlers; the stop path checks `g_MirrorWindow.IsActive()`
and stops unconditionally (cursor-independent).
- `ZoomItSettings.h`: new `MirrorToggleKey` (default `Ctrl+9`) and
`MirrorTrackWindow` settings, added to the `RegSettings[]` table. Record
default kept distinct at `Ctrl+5`.
- `resource.h` / `ZoomIt.rc`: new DemoMirror options tab and controls
(`IDC_MIRROR_HOTKEY`, `IDC_MIRROR_TRACK_WINDOW`).
- `CaptureFrameWait.*` and `SelectRectangle.*` updated to support the
mirror capture/selection flow.
- `ZoomItSettingsInterop/ZoomItSettings.cpp`: exposes the new settings
across the interop bridge.

**Settings UI (WinUI 3)**
- New DemoMirror group on the ZoomIt page (`ZoomItPage.xaml`), backed by
`ZoomItViewModel.cs` and `ZoomItProperties.cs`.
- Localizable strings added to `Resources.resw`.

**Conflict resolution notes** (rebased on top of upstream `main`):
- Control-ID collision resolved by assigning distinct IDs
(`IDC_MIRROR_HOTKEY`, `IDC_MIRROR_TRACK_WINDOW`).
- `SelectRectangle` border-color: kept upstream `m_borderColor =
borderColor;`.
- `WM_USER` message-ID collision resolved by using `WM_USER_MIRROR_STOP
= WM_USER + 113`.

## Validation Steps Performed

Manually validated on a real dual-display setup (Surface laptop extended
to an external monitor):

- **Full screen** (`Ctrl+9`): source screen mirrored to the second
monitor, including the mouse pointer.
- **Region** (`Ctrl+Shift+9`): selected region mirrored correctly. 
- **Window** (`Ctrl+Alt+9`): window under the cursor mirrored; with
**Track window region** enabled, the mirror follows the window.
- **Stop/cancel**: DemoMirror stops reliably regardless of cursor
position; mirror windows never take focus (`WS_EX_NOACTIVATE |
WS_EX_TRANSPARENT`).
- **Hotkey defaults**: confirmed Record (`Ctrl+5`) and DemoMirror
(`Ctrl+9`) defaults are distinct and read independently from their own
registry/settings values (no cross-contamination).
- **Settings UI**: DemoMirror hotkey and Track window region options
round-trip correctly through the Settings UI and the interop bridge.

a64c400b7e [MouseWithoutBorders] Increase PBKDF2 key derivation iterations to 100,000 (#49600)
## Summary
Increases the PBKDF2 iteration count used to derive the Mouse Without
Borders AES-256 session key from 50,000 to 100,000, strengthening the
derived key against brute-force attempts.

## Changes
- `Encryption.cs`: `KeyDerivationIterations` 50,000 -> 100,000 (used by
`GenLegalKey` via `Rfc2898DeriveBytes.Pbkdf2`).

The unrelated SHA-512 stretch loop in `Get24BitHash` is deliberately
left unchanged - it is not a `Rfc2898DeriveBytes` key derivation and
drives the connection framing/identity value.

## Compatibility
This changes the derived key, so all paired machines must run this
version. Mouse Without Borders already requires the same version on
every machine (it surfaces *"make sure you run the same version in all
machines"* on a key/handshake mismatch), consistent with the
per-connection salt/IV change in #48742. The existing key and settings
are preserved and the key is derived fresh per connection, so **no
re-pairing is needed once every machine is updated** - only a transient,
self-healing failure during a mixed-version window.

## Validation
- Built `MouseWithoutBorders` (Release | x64) - clean, exit 0.

160492abcf docs(skills): recommend WindowEx for WinUI 3 migrations (#49303)
## Summary of the Pull Request

Updates the WPF-to-WinUI 3 migration skill to make the established
PowerToys windowing pattern explicit:

- Default WinUI 3 top-level windows to `WinUIEx.WindowEx` or an existing
PowerToys base derived from it, such as `TransparentWindow` for
transient overlays.
- Keep supported size, presenter, title bar, topmost, backdrop, and
persistence behavior declarative in XAML instead of manual `AppWindow` /
`OverlappedPresenter` code-behind.
- Document the centrally managed `<PackageReference Include="WinUIEx"
/>`, WPF-to-`WindowEx` property mappings, and existing repository
examples.
- Add a value-converter decision guide that prefers
`VisualStateManager`, direct `x:Bind` conversion, WinUI theme resources,
and `CommunityToolkit.WinUI.Converters` over mechanically porting WPF
converters.

This follows the migration-skill feedback from @niels9001 in [PR
#49174](https://github.com/microsoft/PowerToys/pull/49174#discussion_r3535181101).

## PR Checklist

- [x] **Communication:** This change follows review feedback from a core
contributor in PR #49174.
- [x] **Tests:** The updated guidance passed 5/5 fresh agent migration
scenarios.
- [x] **Dev docs:** Added/updated.

## Detailed Description of the Pull Request / Additional comments

`SKILL.md` now states the default PowerToys pattern and limits raw
`AppWindow` / presenter code to behavior that `WindowEx` does not
expose. The package mapping reference records the exact centrally
managed dependency. The windowing reference adds a complete XAML
example, a WPF-to-`WindowEx` mapping table, regular-window examples, and
the `TransparentWindow` overlay exception.

The XAML migration reference now also documents converter selection and
reuse: control state belongs in `VisualState`s, count visibility can
share one Toolkit `DoubleToVisibilityConverter` with
`ConverterParameter=True`, and corner-radius converter resources come
from `XamlControlsResources`.

This is an atomic documentation-only change; no product code or
dependencies are modified.

## Validation Steps Performed

- Verified the documented `WindowEx` APIs and `TransparentWindow`
inheritance against the repository and compiled WinUIEx assembly.
- Verified all cited repository paths, the Markdown anchor, and central
package management entry.
- Ran five fresh current-branch agent scenarios; all selected
`<PackageReference Include="WinUIEx" />` without a version, `WindowEx`,
XAML-declared properties, and `CenterOnScreen()` only where required.
- Ran a focused converter migration scenario before and after the
guidance update; the updated skill selected `VisualState`s, one reusable
Toolkit numeric converter, and existing WinUI corner-radius resources
without custom converters.
- Ran `git diff --check` with no errors.
- Completed an independent read-only review with no findings.
- Product builds and unit tests were not run because this change only
updates agent guidance.

8f63402400 PowerDisplay: Adjust brightness by scrolling over the tray icon (#49446)
## Summary of the Pull Request

Scrolling the mouse wheel over the Power Display tray icon adjusts
brightness, without opening the flyout.

- New **Tray icon mouse wheel** setting: `Off` / `Primary display` /
`All displays`, defaulting to **`Off`**. It is scoped to the tray icon —
the flyout sliders accept wheel input regardless, as they always have.
The existing **Mouse wheel increment** setting supplies the per-notch
step.
- **Off by default.** The gesture consumes a wheel notch that would
otherwise reach the window under the pointer, and acting on it installs
a system-wide `WH_MOUSE_LL` hook. Neither is something an existing
installation should acquire silently on upgrade. With the setting `Off`
no hook is ever installed and no notch is ever consumed, so this PR
changes no existing behaviour until the user opts in: 1958 insertions, 2
deletions, and both deletions are refactors of lines this feature
reuses.
- **No feedback UI.** Brightness is self-evidencing — you scroll and the
screen changes — so the display itself is the feedback. The notification
icon is untouched: same tooltip, same text, same legacy
notification-icon protocol.

## Detailed Description of the Pull Request / Additional comments

### Why a low-level hook

The Shell does not forward `WM_MOUSEWHEEL` to a notification icon's
callback window under any `NOTIFYICON_VERSION`, and a click-through
overlay placed over the icon cannot receive wheel input either.
`TrayIconMouseWheelListener` therefore installs a `WH_MOUSE_LL` hook —
but only transiently, and only when it will act on the result:

- Nothing is installed at all while the setting is `Off`, which is the
default.
- Installed in `EnsureHook()` when the UI thread confirms the pointer is
inside the rectangle from `Shell_NotifyIconGetRect` **and**
`CanAdjustBrightnessFromTrayWheel` says some monitor can accept a
brightness write.
- Removed in `DisarmCore()` as soon as either condition stops holding,
the pointer leaves the rectangle, or the mode changes.
- A notch is consumed (the hook proc returns non-zero) only while armed
and only for points inside the armed rectangle, so a wheel event Power
Display will not act on still reaches the window under the cursor.

The hook runs on a dedicated background thread with its own message
loop; the proc itself only enqueues a sample and posts a drain request.
Deltas are marshalled to the UI thread in batches, and
`WheelDeltaAccumulator` folds high-resolution deltas (precision wheels,
touchpads) into whole notches. Each sample carries the hover generation
it was captured under, so samples from a hover the UI thread has already
retired are discarded rather than applied late.

### Hover detection

The Shell sends `WM_MOUSEMOVE` to the icon's callback window while the
pointer is over it. `TrayIconService.HandleTrayMouseMove` resolves the
rectangle with `Shell_NotifyIconGetRect` and caches it for a second,
because that message repeats for every pixel of travel.

`TrayIconService` gains nothing else: no protocol change, no new hover
UI, no polling. The rest of the file — and `MainWindow.xaml` — is
untouched.

### Linked brightness

While linked brightness is on, a notch has to move the whole group, so
it goes through `MainViewModel.LinkedBrightness` rather than the
individual monitor setters. The new master value is taken from the
planner's value for the monitor the wheel named, **not** from the
current master. The master is positional only —
`SeedInitialLinkedBrightness` takes it from the lowest-numbered linked
monitor and never writes hardware, and every monitor-list rebuild
re-seeds it — so it can sit arbitrarily far from the monitor the wheel
is aimed at. Stepping it relative to itself would apply a wrong-sized or
wrong-signed change, and a master already clamped at 0/100 would swallow
the notch while writing nothing at all.

The setting description calls out that linked brightness widens the
scope, so `Primary display` is not literally a single display while it
is on.

### What is deliberately not here

An earlier revision of this PR showed the target and percentage in a
custom overlay as you scrolled. Doing that meant the standard Shell
tooltip would not do (it cannot be shown on demand), which meant an own
window, which meant suppressing the Shell tooltip so the two did not
collide, which meant `NOTIFYICON_VERSION_4`, which changed the callback
packing and made the app responsible for all hover text — including for
keyboard and touch users, who never reach a cursor-anchored overlay and
would have been left with no visible tooltip at all.

That chain was about half the diff, for a readout that adds little on
top of watching the screen change. It is gone. If a readout is wanted
later it can be argued on its own merits, separately from this feature.

The same revision also gated the flyout sliders on this setting. That
bundled two unrelated things behind one switch — turning off tray
scrolling would also have stopped the contrast and volume sliders
responding to the wheel — so the setting is now scoped to the tray icon
and named accordingly.

An earlier revision also routed the tray **Exit** action through
`Shutdown()`. That fixes a pre-existing teardown leak which has nothing
to do with this feature, so it now lives in #49580 and is out of scope
here. This branch does not depend on it: the hook thread is a background
thread and the process is ending either way.

## Validation Steps Performed

- Unit tests: `PowerDisplay.Lib.UnitTests` 215 passed,
`Settings.UI.UnitTests` 165 passed.
- Builds: `PowerDisplay` and Settings UI, x64 Debug, no warnings.
- Automated coverage is in `PowerDisplay.Lib.UnitTests`: target
selection per mode, wheel accumulation including negative deltas,
partial notches and direction reversal, half-open rectangle containment,
and settings serialization and round-trip for the new mode, including
that a settings file predating the feature loads as `Off`.
`Settings.UI.UnitTests` covers the view-model index mapping and pins the
enum values to the ComboBox item order.
- The Win32 glue in `TrayIconService` and `TrayIconMouseWheelListener`
is not unit tested.

Manual passes performed: scrolling over the icon in both modes, the icon
parked in the notification overflow, high-resolution wheel input,
brightness boundaries, live monitor refresh while hovering, tray icon
hidden and re-enabled, Explorer restart, the context menu and
left-click, `Off` stopping tray scrolling while the flyout sliders keep
working, and confirming a notch that Power Display will not act on still
reaches the window under the cursor.

Not verified, needing hardware this branch has not been run on:

- Multiple taskbars, where the tray icon is on a secondary display and
`Primary display` mode adjusts a monitor the user may not be looking at.
- Mixed-DPI setups, for the `Shell_NotifyIconGetRect` rectangle and the
hook's physical-pixel hit test.

3cb3bdcd34 PowerDisplay: Reuse the values the max-compatibility probe already read (#49596)
## Summary of the Pull Request

In Maximum compatibility mode, when a monitor's capabilities string is
unusable, discovery probes each continuous VCP code directly to find out
which ones the panel implements — and then **throws the values away**.
`BuildMonitorFromPhysical` immediately re-reads every one of those
codes.

That doubles the I2C traffic on exactly the hardware that cannot take
it, and the re-read is the one whose result the user actually sees: a
panel that answered the probe a moment ago but fails the re-read shows
its brightness slider parked at the never-read default instead of where
the panel really is.

This makes the probe's values survive into the build stage.

Extracted from #49445, which bundles it with a persisted discovery cache
it does not depend on.

## Detailed Description of the Pull Request / Additional comments

### What the re-read costs

Worth being precise about, because it is not the slider's *existence*:

| decided by | set from | affected by a failed re-read |
| --- | --- | --- |
| slider visible (`MonitorViewModel.ShowBrightness`) |
`Monitor.Capabilities`, via `UpdateMonitorCapabilitiesFromVcp` before
the initializer runs | no |
| slider position (`Monitor.CurrentBrightness`) | the read | yes — stays
at the never-read default |
| `powerdisplay get` reporting a live reading (`Monitor.ReadValues`) |
the read | yes — reported as unknown |
| relative `powerdisplay adjust` (`AdjustCommandExecutor`) |
`Monitor.ReadValues` | yes — no before-value to adjust from |

So the flyout keeps the control either way; what the second read decides
is whether it is pointed anywhere real, and whether the CLI will admit
to a value. Halving the transactions on a bus that is both slow and, on
this hardware, unreliable is the other half of the win.

### The seam

`FetchCapabilitiesWithFallbackAsync` used to return `(string capsString,
VcpCapabilities? caps)` — capabilities only, no values. It now returns a
`VcpDiscoveryEvidence`, which carries the same two things plus the
values the probe already read and a flag for a handle that died
mid-probe.

`VcpDiscoveryEvidence.Reconcile` folds the probe observations into the
parsed capabilities in one place:

| observation | capabilities | value carried |
| --- | --- | --- |
| read succeeded | code marked supported | yes |
| device replied, range unusable (e.g. `max=0`) | code marked supported
| no — the initializer still owes it a read |
| no reply | unchanged | no |
| handle-class failure | everything discarded | — |

The second row is why membership keys off `Replied` rather than the
value being usable: an unimplemented code fails with
`DDCCI_VCP_NOT_SUPPORTED` and never sets the flag, so a reply proves the
opcode exists even when the reported range cannot scale a percentage.
That is the same rule `BuildCapabilitiesFromProbe` used before this PR;
it just moves next to the value handling.

Like that method, `Reconcile` iterates the observations rather than
`NativeConstants.ContinuousVcpCodes`, which `VcpFeatureProbeService`
only takes as the default for its constructor-injected sweep list. That
keeps a widened sweep from silently dropping a code that answered, but
it is not sufficient on its own: the carried value is consumed only for
codes `ContinuousVcpInitializer` walks, so widening the sweep still
needs a matching edit there. The comment and
`Reconcile_ProbedCodeOutsideTheDefaultSweepIsStillHonoured` both say so
rather than claiming the seam alone covers it.

On the normal path nothing changes: the probe only runs when the caps
string is unusable, so `live` is empty and `Reconcile` is a
pass-through. `Reconcile_ParsedCapabilitiesSurviveWhenNoProbeRan` pins
that.

### Continuous-VCP initialization moves out of the controller

`DdcCiController` carried six near-identical `Initialize*` methods. The
three percent-scaled ones become **`ContinuousVcpInitializer`** —
brightness, contrast, volume. It skips any code the evidence already has
a value for, and returns `false` when a read fails with a handle-class
error, because `Monitor.Handle` is captured once per discovery pass and
never refreshed: a monitor kept alive on a dead handle would send every
later read and write into the void.

It reads through the `IVcpFeatureReader` seam introduced in #49579, so
it is testable without hardware.

The three discrete-enum ones — color preset, input source, power mode —
stay in `DdcCiController`, unchanged. The probe sweeps only
`NativeConstants.ContinuousVcpCodes`, so no discrete value is ever
carried across the seam and extracting them would be a refactor this
change does not need; see *What is deliberately left out*.

Only the continuous stage discards the monitor. That is a policy choice,
not a property of the stage: losing a whole display because `0xD6`
answered badly is worse than showing it without a power control.

`DdcCiController.TryGetVcpFeature` therefore still has three discovery
callers plus `GetVcpFeatureAsync`, the runtime refresh path.

### Behaviour change outside Maximum compatibility mode

**A handle-class error during continuous VCP initialization now discards
the monitor.** Before, the failure was logged, the read flag left unset,
and the monitor kept — so its handle reached
`PhysicalMonitorHandleManager` and every later operation went to a
handle already known to be dead. The cost is that the monitor stays out
of the flyout until a rediscovery: `DisplayChangeWatcher` schedules one
for device-arrival/removal and console-display-state notifications, and
the flyout's Refresh button forces one on demand.

Note this check is not on every path. A caps string that parses but
advertises none of `0x10`/`0x12`/`0x62` leaves
`ContinuousVcpInitializer` nothing to read and suppresses the probe, so
such a monitor is still published with a handle no VCP read has
exercised — and its first VCP read then happens in the discrete stage,
which never discards.

### What is deliberately left out

**Extracting the discrete-VCP initialization.** The probe sweeps only
the continuous codes, so no discrete value is ever reused and moving
`0x14`/`0x60`/`0xD6` out of the controller would be a drive-by refactor
with no bearing on this change. It is worth doing on its own, where the
added test coverage can be reviewed for what it is.

**Remembering a probe value across discoveries.** A probe value is only
useful for the pass that produced it. Carrying one forward — so a later
failing pass can still show the control — is the persisted known-good
cache in #49445, a much larger change with an open design question
attached. This PR is complete without it.

## Validation Steps Performed

- built `PowerDisplay.Lib.UnitTests` and `PowerDisplay` for x64 Debug
with VS MSBuild — 0 errors, 0 warnings
- ran `PowerDisplay.Lib.UnitTests.dll` with `vstest.console.exe`: **240
passed, 0 failed** — 16 of those cases are added here (8 in
`ContinuousVcpInitializerTests`, 7 in `VcpDiscoveryEvidenceTests`, 1 in
`DdcErrorClassifierTests`)
- `VcpDiscoveryEvidenceTests` pins each row of the table above, plus
that a probed code outside the default sweep is still honoured
- `ContinuousVcpInitializerTests` pins that a probed code is never
re-read (the reader is primed with a failure it must not reach), that a
handle-class error stops the remaining codes, and that a feature-level
refusal does not. `Initialize_EveryContinuousCodeIsReadAndApplied` walks
the whole `ContinuousVcpCodes` array with a distinct range and
percentage per feature, so a code added to that array without an arm in
both `IsSupported` and `ApplyValue` fails rather than being silently
skipped or silently discarded — checked by mutation: removing either
volume switch arm fails that test and
`Initialize_ProbedVolumeIsAppliedWithoutReadingAgain`
- not covered by tests: the `DdcCiController` side of the contract —
that `evidence.IsPhysicalMonitorUnavailable` skips the monitor and
releases the physical, and that a `false` from
`ContinuousVcpInitializer` does the same. That layer takes no injectable
dependencies today
- no hardware validation performed: this path is reachable only on a
panel whose capabilities string is unusable, which needs an incomplete
or unreliable DDC/CI implementation

ffc839afea [PowerAccent] Fix injection hygiene and reset state on hide (#48572)
## Summary
Keeps Quick Accent-injected keys from retriggering centralized shortcuts
and clears native keyboard-listener state whenever the toolbar closes.

## What this changes
- Tags backspace, Unicode, and arrow `SendInput` events with
`dwExtraInfo = 0x110`, mirroring
`CENTRALIZED_KEYBOARD_HOOK_DONT_TRIGGER_FLAG`.
- Uses the existing `SendArrowKey(bool)` implementation as the single
arrow-injection path, preserving `KEYEVENTF_EXTENDEDKEY` on key-down and
key-up.
- Checks the number of events sent by every `SendInput` call and logs
incomplete sends.
- Adds `ForceReset()` to the keyboard service WinRT API and invokes it
from the core hide path immediately before `OnChangeDisplay(false)`.
- Keeps listener state non-atomic because the low-level hook is
installed on the WinUI thread and its callbacks execute on that same
thread, as documented by `MainWindow.RunOnUiThread`.

## Testing
- Built `PowerAccent.Core.csproj` in Release x64, including
`PowerAccentKeyboardService`.

70e0fc2295 CmdPal: when expanding compact mode, don't be too tall (#49532)
If you open command palette on one display and resize its expanded size
to be very tall, then you move command palette to a monitor that is not
that tall and expand it, we will still expand our control to fit the
full size of our HWND, which is taller than this new monitor. This PR
fixes that by making sure to measure the size that's available on the
current monitor and limit the max height of our control when we're
expanding it, so that the bottom of the control always fits on the
current monitor.

7d1dde7aa5 [ZoomIt] Port recording/editing features from Mac ZoomIt (trim editor, snip-to-clipboard, recording border) and fix video trim reliability (#49553)
## Summary of the Pull Request

Ports several recording and editing features from the Sysinternals **Mac
ZoomIt** into the Windows PowerToys ZoomIt module, and hardens the video
**trim/save** pipeline against a sporadic "Failed to trim the video"
failure.

Highlights:
- **Video trim editor — interior "Delete Region" editing.** In the
post-recording trim dialog you can now select and delete interior
segments (not just trim the head/tail). Includes red timeline overlays
with drag grips, right-drag to select, `Delete` to remove, `Ctrl+Z` to
undo, and `Esc` to cancel a pending selection.
- **Reliable trim/render.** Fixed a sporadic *"Failed to trim the
video"* error. The live capture pipeline produces **fragmented** MP4s
(moof/mdat) that play in preview but fail `MediaComposition` render/seek
with `0xC00DA7FC`. The render path now (a) sources resolution from the
clip's encoding properties first, (b) retries transient failures (0×0
dimensions from a fragmented-MP4 metadata race, `!CanTranscode()`,
post-remux render failure), and (c) remuxes fragmented MP4s to a
standard seekable MP4 via `MediaTranscoder` before rendering.
- **Snip → Copy to clipboard.** New ZoomIt setting to copy a snip
directly to the clipboard.
- **Recording border color.** The screen-recording selection border now
uses a distinct color, and turns orange while recording is active.
- **GIF recording robustness.** First-frame timeout so GIF capture
doesn't hang when no frames arrive.
- **Audio hardening.** Stereo downmix handling and defensive guards in
the audio sample generator.
- **Opt-in diagnostics.** Recording diagnostics (`[RecDiag]`) are gated
behind a registry DWORD
`HKCU\Software\Sysinternals\ZoomIt\EnableDebugTrace` (off by default),
and all module debug output is prefixed with `[ZoomIt]` for easy
filtering in DebugView.
- **Fix:** GDI bitmap leak in the snip-to-clipboard path when
`SetClipboardData` fails.

## PR Checklist

- [ ] **Tests:** ZoomIt is native Win32/WinRT with no unit-test harness;
validated manually (see Validation Steps)
- [ ] - [x] **Localization:** All end-user-facing strings can be
localized <!-- new strings added to Settings.UI en-us Resources.resw -->
- [ ] **Dev docs:** Added/updated
- [ ] **New binaries:** N/A: no new binaries/projects 
  - [ ] JSON for signing — N/A
  - [ ] WXS for installer — N/A
  - [ ] YML for CI pipeline — N/A

## Detailed Description of the Pull Request / Additional comments

Files changed (17):

**ZoomIt module (native)**
- `VideoRecordingSession.cpp/.h` — interior delete-region trim editor;
render/trim reliability (resolution from clip encoding properties, retry
loop, fragmented-MP4 → seekable remux); registry-gated `[RecDiag]`
diagnostics.
- `GifRecordingSession.cpp` — first-frame timeout / no-frames handling.
- `AudioSampleGenerator.cpp` — stereo downmix + defensive guards.
- `SelectRectangle.cpp/.h`, `PanoramaCapture.cpp` — recording border
color parameter.
- `Zoomit.cpp` — snip → clipboard workflow; GDI bitmap leak fix on
`SetClipboardData` failure.
- `ZoomItSettings.h`, `ZoomIt.h`, `ZoomIt.rc`, `resource.h` — new
setting + "Delete Region" button + message id.
- `pch.h` — `[ZoomIt]` debug-output prefix wrapper.

**Settings UI**
- `ZoomItProperties.cs`, `ZoomItViewModel.cs`, `ZoomItPage.xaml`,
`Resources.resw` — "Copy snip to clipboard" setting and localized
strings.

Note: ZoomIt is a Sysinternals port kept in its upstream code style, so
it is intentionally exempt from the repo `.clang-format` (changed lines
follow the surrounding Sysinternals convention).

## Validation Steps Performed

Manual validation (no automated ZoomIt harness):
- **Trim reliability:** Recorded multiple clips and used Trim → Save
repeatedly (including 3-clip compositions produced by Delete Region);
render now succeeds consistently (previously failed sporadically with
"Failed to trim the video").
- **Delete Region editor:** Right-drag to select an interior segment,
`Delete` to remove, `Ctrl+Z` to undo, `Esc` to cancel; saved output
reflects the removed segments.
- **Snip → clipboard:** Enabled the new setting; snip is placed on the
clipboard and pastes correctly. Verified no GDI handle leak when
clipboard set fails.
- **Recording border:** Verified border color and the orange
active-recording state (full-monitor and region).
- **GIF:** Confirmed capture no longer hangs when no frames arrive.
- **Diagnostics:** With `EnableDebugTrace` unset, no
`%TEMP%\ZoomIt_RecDiag.log` and no `[RecDiag]` output; with it set to
`1`, `[ZoomIt] [RecDiag ...]` traces appear.
- **Style checks:** XamlStyler (clean), StyleCop via building
`Settings.UI.Library` and `PowerToys.Settings` (no `SA####` warnings),
ZoomIt x64 Release builds with exit code 0.

5803bc7ec5 BUILD: Fix the version.vcxproj FastUpToDate check (#49534)
This has been my personal enemy for a year now.

VS will skip doing work for your build if it thinks everything is up-to-
date. But this version project has been treated as dirty for a long time
now. What that means is that incremental builds (READ: dev inner loop
builds) end up building the world CONSTANTLY. Because VS thinks FOR SOME
REASON that this project needs to rebuild.

By setting the `Inputs`/`Outputs` for this `Target`, VS is smart enough
to only re-run the task if the inputs actually changed since the last
build.

Tested by building the code, then building again, and observing that
all the projects were successfully noted as up-to-date

drive-by: fix some of the other `csproj` files for cmdpal.

4b3f961b12 [PowerDisplay] Run the tray Exit through Shutdown so teardown is not skipped (#49580)
## Summary of the Pull Request

PowerDisplay's tray context menu **Exit** ended the process with
`Environment.Exit(0)`, skipping the teardown that `App.Shutdown()`
already
performs. Point it at `Shutdown()` instead — a one-line change.

What Exit was skipping:

- `TrayIconService.Destroy()` — `Shell_NotifyIcon(NIM_DELETE)`, the icon
and
popup-menu handles, and restoring the subclassed window procedure.
Without the
`NIM_DELETE`, the notification area can keep showing a stale
PowerDisplay icon
until the Shell next validates it, which in practice is when the pointer
passes
  over it.
- `MainWindow.Dispose()` — which cancels the CLI named-pipe server's
`CancellationTokenSource` and disposes the hotkey service, the message
hook and
`MainViewModel` (monitor manager, display-change watcher, per-monitor
view
  models).

`Environment.Exit` does not run finalizers, so none of that happened by
another
route.

The named-pipe terminate message (`PowerDisplayTerminateAppMessage`) has
always
gone through `Shutdown()`, so this only makes the tray menu agree with a
path
that is already shipping. The tray menu command is dispatched from the
subclassed main-window procedure, so it already runs on the UI thread
that owns
these objects, and `Shutdown()` still ends with `Environment.Exit(0)` —
the
process exits unconditionally either way.

## PR Checklist

- [ ] Closes: #xxx — no filed issue. Found while working on #49410;
split out so
      it can be reviewed on its own.
- [ ] **Communication:** I've discussed this with core contributors
already. If
      the work hasn't been agreed, this work might be rejected
- [ ] **Tests:** Added/updated and all pass — none added. The change is
process-exit wiring inside `App.OnLaunched`, which has no test harness;
      validated manually.
- [x] **Localization:** All end-user-facing strings can be localized —
no new or
      changed strings.
- [ ] **Dev docs:** Added/updated — no doc change warranted for a
one-line
      teardown fix.
- [ ] **New binaries:** Added on the required places — none.
- [ ] **Documentation updated:** no user-facing behaviour change.

## Detailed Description of the Pull Request / Additional comments

### Deliberately not in scope

Two other paths still call `Environment.Exit(0)` directly, and both are
pre-existing and unchanged here:

- The runner **Terminate** event
(`Constants.TerminatePowerDisplayEvent()`) —
the module-disable and PowerToys-exit path. Its callback is already
marshalled
to the UI thread by `NativeEventWaiter`, so it *could* be routed the
same way,
but adding teardown work to the runner's shutdown path should be
validated
against the runner's shutdown timeout on its own rather than riding
along with
  a tray-menu fix.
- The `RunnerHelper.WaitForPowerToysRunner` watchdog, whose callback
runs on a
  background thread and would need marshalling to the UI thread first.

Happy to follow up on either if reviewers would rather see them fixed
together.

## Validation Steps Performed

- Tray icon → right-click → **Exit**: PowerDisplay exits, the
notification icon
  disappears immediately rather than lingering until hover.
- Re-launch from PowerToys Settings after a tray Exit: the tray icon
comes back
  once, not twice.
- `powerdisplay` CLI still works after a launch/tray-Exit/launch cycle,
confirming the named pipe was released rather than left to process
teardown.
- Existing terminate paths unchanged: disabling PowerDisplay in Settings
and
  quitting PowerToys both still exit the process.

bc2d09abe8 PowerDisplay: Pace and retry the maximum-compatibility VCP probe (#49579)
## Summary of the Pull Request

In Maximum compatibility mode, when a monitor's capabilities string is
missing or unparsable, discovery falls back to probing each continuous
VCP code directly. That probe issues **one**
`GetVCPFeatureAndVCPFeatureReply` per code, back to back, and treats any
failure as final. On a panel whose DDC/CI engine answers intermittently,
a single transient I2C fault permanently drops that control for the
whole discovery pass — and if every code happens to fault, the monitor
disappears from the flyout entirely.

This replaces the probe with `VcpFeatureProbeService`:

- **paced** — 100 ms between transactions, instead of hammering the I2C
bus back to back
- **retried** — up to 3 attempts, but only for failures another attempt
can plausibly get past
- **classified** — `DdcErrorClassifier` decides what "transient" means,
so the retry budget is not burned on a definitive
`DDCCI_VCP_NOT_SUPPORTED` or on a dead physical-monitor handle
- **aborted early** — a handle-class error stops the remaining codes
rather than issuing more requests against a handle already known to be
invalid

Extracted from #49445, which bundles this with a persisted discovery
cache and a discovery restructure it does not depend on. This piece
stands alone and addresses one of the root causes in #49342 by itself.

## PR Checklist

- [ ] Closes: #xxx — partially addresses #49342; the remaining causes
are in #49445
- [ ] **Communication:** I've discussed this with core contributors
already. If the work hasn't been agreed, this work might be rejected
- [x] **Tests:** Added/updated and all pass
- [x] **Localization:** All end-user-facing strings can be localized —
this PR adds none
- [ ] **Dev docs:** Added/updated
- [x] **New binaries:** Added on the required places — none added; no
new project, so no signing JSON, installer WXS or CI YML change is
required
- [ ] **Documentation updated**

## Detailed Description of the Pull Request / Additional comments

### What is and is not retried

`DdcErrorClassifier` names the DDC/CI error codes after `winerror.h` and
splits them into two sets. `DdcErrorClassifierTests` pins both the
membership of each set **and** the numeric value of every constant
against `winerror.h`, so a typo cannot move production and tests
together and leave the suite green.

Retried — framing, arbitration and timing faults on the I2C bus:
`I2C_ERROR_TRANSMITTING_DATA`, `I2C_ERROR_RECEIVING_DATA`,
`DDCCI_INVALID_DATA`, `MCA_INTERNAL_ERROR`,
`DDCCI_INVALID_MESSAGE_COMMAND`, `DDCCI_INVALID_MESSAGE_LENGTH`,
`DDCCI_INVALID_MESSAGE_CHECKSUM`,
`DDCCI_CURRENT_CURRENT_VALUE_GREATER_THAN_MAXIMUM_VALUE`,
`ERROR_TIMEOUT`.

Not retried, each for a stated reason recorded on the predicate:
`DDCCI_VCP_NOT_SUPPORTED` is the device's final answer;
`I2C_NOT_SUPPORTED` and `I2C_DEVICE_DOES_NOT_EXIST` are permanent
bus-level facts; `MCA_INVALID_CAPABILITIES_STRING` belongs to the
capabilities path, not to a VCP read; and the two handle-class codes
must abort rather than retry.

### Behaviour preserved

`FetchCapabilitiesWithFallbackAsync` keeps its signature and still
returns `(string, VcpCapabilities?)`, so nothing outside the probe
changes. `BuildCapabilitiesFromProbe` synthesizes the same shape
`DdcCiNative.ProbeSupportedVcpFeatures` used to, and decides membership
the same way: a code counts as supported when the device *replied*, not
when the value was usable. A reply proves the opcode is implemented even
if the reported range cannot scale a percentage — an unimplemented code
fails with `DDCCI_VCP_NOT_SUPPORTED` instead.

The set of probed codes moves from a private array in `DdcCiNative` to
`NativeConstants.ContinuousVcpCodes`, where the follow-up work in #49445
also needs it.

### Cost

The probe only runs in Maximum compatibility mode, and only when the
capabilities string is already unusable — so this adds no I2C traffic to
a monitor that parses normally. For a monitor that does reach it, the
worst case grows from 3 transactions to 9 plus 900 ms of pacing, and it
is bounded: a definitive refusal stops after one attempt, and a
handle-class error stops the whole probe.

### What is deliberately left out

The probe's values are still discarded — `BuildMonitorFromPhysical`
re-reads each code immediately afterwards. Reusing them needs a carrier
for the observed value, which is `VcpDiscoveryEvidence` in #49445.
`VcpFeatureProbeService` already returns everything that needs
(`VcpProbeObservation` carries the value, the attempt count and the last
error); this PR simply does not consume it yet.

## Validation Steps Performed

- built `PowerDisplay.Lib.UnitTests` for x64 Debug with VS MSBuild — 0
errors, 0 warnings
- ran `PowerDisplay.Lib.UnitTests.dll` with `vstest.console.exe`: **223
passed, 0 failed** (186 on `main` + 37 added here)
- `VcpFeatureProbeServiceTests` drives the pacing, the retry budget, the
transient/definitive split, cancellation before and during the
inter-transaction delay, a throwing native read, and that reads run off
the caller's thread — all through an injected reader and an injected
delay, so no hardware is needed
- no hardware validation performed: reaching this path needs a panel
whose capabilities string is unusable **and** whose VCP reads fail
intermittently

efc0258cda Validate the update installer before PowerToys.Update launches it (#48903)
## Summary

PowerToys' self-updater downloads the installer into
`%LOCALAPPDATA%\Microsoft\PowerToys\Updates` and then launches it from
`PowerToys.Update.exe` (Stage 2). This makes that launch path more
robust:

- Open the downloaded installer with a read-only share so the file stays
consistent while we inspect and run it.
- Confirm it is a valid, Authenticode-signed **Microsoft** PowerToys
installer (valid signing chain + Microsoft organization) before
executing it. This single chokepoint covers both freshly downloaded and
previously downloaded installers.
- If the check does not pass, log and skip the launch instead of running
an incomplete or invalid file.

## Implementation

- Added `updating::verify_installer_trust` to the shared
`common/updating` library (`installer.h` / `installer.cpp`):
`WinVerifyTrust` for the signing chain, and `CryptQueryObject` /
`CertGetNameString` to confirm the signer's organization is `Microsoft
Corporation`. `Wintrust.lib` / `Crypt32.lib` are linked via `#pragma
comment(lib, ...)`.
- `InstallNewVersionStage2` opens the installer with `FILE_SHARE_READ`,
verifies it, and keeps the handle open across `MsiInstallProductW` / the
bootstrapper launch so the file stays stable during install.

## Validation

- `ApplicationUpdate` and `PowerToys.Update` build clean (x64 Debug).
- Existing updating unit tests pass (30/30).
- Checked end-to-end against real binaries: a Microsoft
Authenticode-signed binary is accepted; a corrupted copy and an unsigned
file are both declined.

af5665eaa8 PowerDisplay: Always write the saved value when restoring monitor settings (#49577)
## Summary of the Pull Request

`TryRestore` skipped writing a saved monitor value when it already
equalled the value `MonitorViewModel` was showing. That displayed value
is only an observation when the discovery-time VCP read succeeded. When
the read failed it is a placeholder:

| setting | value when the read failed | source |
| --- | --- | --- |
| brightness | `50` | `MonitorDiscoveryHelper` stamps it — *"Initial
placeholder; overwritten if the VCP read succeeds"* |
| contrast | `50` | `Monitor` backing-field default |
| volume | `50` | `Monitor` backing-field default |
| color temperature | `0x05` (6500K) | `Monitor` backing-field default |

A saved value that happened to equal one of those silently suppressed
the restore, and the monitor kept whatever it powered on with. `50` is
the mid-slider value and `0x05` is the most common preset, so the
coincidence is not rare.

This drops the comparison: a restore now always writes.

## Detailed Description of the Pull Request / Additional comments

### Why remove the check rather than refine it

The skip-if-equal check dates from PowerDisplay's first commit (#42642,
where it read `// Restore brightness if different from current`); #47051
only refactored it into the shared `TryRestore` helper. It is day-one
"obviously we shouldn't write twice" code, not a response to a reported
problem.

Removing it is correct by construction: with no skip branch there is no
state in which a restore silently does nothing. Any narrower fix has to
decide *when* the displayed value can be trusted, and gets that decision
wrong in exactly the cases that are hardest to reproduce.

### Cost

Two, both bounded:

- **A redundant VCP write when the monitor already sits at the saved
value.** Some panels surface a write on their OSD. Both paths that reach
here are user-initiated: startup restore only runs when
`RestoreSettingsOnStartup` is enabled, and a profile apply happens
because the user invoked that profile.
- **Time.** At most four writes per monitor, serialised on that
monitor's I2C bus (~100 ms each). Monitors still run in parallel through
the existing `Task.WhenAll`.

The `isVisible` guard is untouched, so a monitor still never receives a
write for a feature it does not expose — an unsupported VCP `0x14` is
not written just because a profile carries a color temperature. Input
source and power state are not restored here at all.

### If the redundant write turns out to matter

The narrower fix is to keep the comparison and add one clause: also
write when `(monitor.ReadValues & flag) != flag`, i.e. when the compared
value was never read off the hardware. `MonitorReadFlags` already
carries exactly that information, and `Monitor.ReadValues` is already
maintained by the discovery-time `Initialize*` methods, so it is a small
change on top of this one. I went with the simpler version first — happy
to switch if a maintainer would rather keep the optimisation.

## Validation Steps Performed

- built `PowerDisplay` and `PowerDisplay.Lib.UnitTests` for x64 Debug
with VS MSBuild — 0 errors, 0 warnings
- ran `PowerDisplay.Lib.UnitTests.dll` with `vstest.console.exe`: **186
passed, 0 failed** — unchanged from `main`; this PR touches only the app
project and adds no tests
- no hardware validation performed: the placeholder path this PR fixes
is reachable only on a monitor whose VCP read fails during discovery

32f738bd45 PowerDisplay: Release physical-monitor handles that discovery abandons (#49578)
## Summary of the Pull Request

`DdcCiController.DiscoverFromHandleAsync` abandons a physical monitor on
three paths without destroying its handle.

Handles only reach `PhysicalMonitorHandleManager` through monitors that
were successfully built: the map is rebuilt from the returned monitor
list, and its cleanup pass only destroys handles that were in the
*previous* map. A handle dropped on an abandon path therefore never gets
destroyed. A discovery runs on every display-topology change, so a
monitor that keeps failing leaks one more handle per discovery for the
process lifetime — a docking-station user accumulates them.

Extracted from #49445, where the same fix is bundled with
maximum-compatibility-mode work it does not depend on.

## Detailed Description of the Pull Request / Additional comments

### The three leaking paths

| path | before this PR |
| --- | --- |
| more physical monitors than `QueryDisplayConfig` entries for the GDI
name | `break` leaves `physicals[i..]` unreleased — the whole tail, not
just the current one |
| capabilities unavailable | `continue` |
| `BuildMonitorFromPhysical` returned null (construction failed, or it
threw and was caught) | no `else` branch at all |

`ReleaseAbandonedPhysical` is null-handle safe and swallows a failing
`DestroyPhysicalMonitor` at warn level: one handle that cannot be
destroyed must not take down the rest of the discovery pass.

### Why there are no tests

Reaching these call sites means faking the whole native enumeration
surface — `EnumDisplayMonitors`, `GetMonitorInfo`,
`GetPhysicalMonitorsFromHMONITOR` — which is a larger seam than a
one-file leak fix should introduce. The paths were verified by reading
instead. Happy to add the seam if a maintainer would rather have it
covered.

### Known remaining leaks, deliberately out of scope

- `GetPhysicalMonitorsWithRetryAsync`'s retry loop discards a whole
array of live handles when it retries after seeing NULL handles.
- Cancellation unwinds `DiscoverMonitorsAsync` before `UpdateHandleMap`
runs, so that pass's handles never enter the map and are never
destroyed.

Both predate this change and are better addressed separately.

## Validation Steps Performed

- built `PowerDisplay.Lib` and `PowerDisplay.Lib.UnitTests` for x64
Debug with VS MSBuild — 0 errors, 0 warnings
- ran `PowerDisplay.Lib.UnitTests.dll` with `vstest.console.exe`: **186
passed, 0 failed** — no new tests; this only confirms nothing regressed
- no hardware validation performed: reaching an abandon path needs a
monitor whose capabilities fetch fails or whose construction throws

d72fa2ea6e Update Monaco Editor from 0.47.0 to 0.52.2 (#48415)
## Summary of the Pull Request

Updates the vendored Monaco Editor from 0.47.0 (Mar 2024) to 0.52.2 (Dec
2024).

## PR Checklist

- [x] **Communication:** Discussed in #46692 review
- [x] **Tests:** Headless-browser smoke tests pass (syntax highlighting,
custom languages, context-menu hack, addAction registration)
- [x] **Dev docs:** No doc changes needed (update process unchanged)

## Detailed Description

### What changed

| Area | Detail |
|------|--------|
| `src/Monaco/monacoSRC/min/` | Replaced with `monaco-editor@0.52.2`
from npm |
| NLS layout | `editor.main.nls.*.js` / `simpleWorker.nls.*.js` removed
upstream → `vs/nls.messages.*.js` added |
| New language | `typespec` shipped upstream (+1 language, 100→101
total) |
| `monacoSpecialLanguages.js` | Inline grammar snapshots
(cpp/xml/razor/vb/ini/shell) refreshed from 0.52.2 shipped files |
| `monaco_languages.json` | Regenerated; all PowerToys custom languages
+ extension mappings intact |

### Supply-chain verification

- npm tarball SHA-512 verified against registry SRI:
`sha512-GEQWEZmfkOGLdd3XK8ryrfWz3AIP8YymVXiPHEdewrUq7mh0qrKrfHLNCXcbB6sTnMLnOZ3ztSiKcciFUkIJwQ==`
- Vendored tree hash-verified file-by-file (103 files, all match)

### Why 0.52.2 and not 0.55.1 (latest)?

Monaco 0.53+ completely restructured the `min/` bundle: flat hashed
chunks instead of per-language AMD modules,
`vs/platform/actions/common/actions` removed,
`vs/basic-languages/<id>/<id>` modules eliminated. PowerToys'
`index.html` (context-menu stripping via MenuRegistry) and
`monacoSpecialLanguages.js` (language cloning via AMD require) depend on
these internals. **0.52.2 is the last release compatible without a
glue-code rewrite.** The 0.55.x port is tracked separately.

## Validation Steps Performed

- [x] Tarball SRI integrity verified against npm registry
- [x] Vendored tree == tarball (SHA-256 per file, 103/103 match)
- [x] `monacoSpecialLanguages.js` passes Node.js syntax check
- [x] Headless smoke test (Edge via puppeteer-core): editor creates,
tokenization paints (5+ classes), `addAction` entries register,
`MenuRegistry` context-menu hack works
- [x] Same smoke test passes identically on 0.47.0 baseline (no
regressions)
- [x] `monaco_languages.json`: 101 languages, all custom IDs present
(reg, gitignore, srt, cppExt, xmlExt, txtExt, razorExt, vbExt, iniExt,
shellExt)

## Related

- Supersedes automation approach in #46692 (which has fatal bugs; will
close separately)
- 0.55.x port tracked as follow-up issue

d127511c7d Fix runner APPLICATION_HANG_QUIESCE: handle WM_ENDSESSION and skip blocking shutdown cleanup (#48363)
## Summary

The runner WndProc (`tray_icon_window_proc`) does not handle
`WM_QUERYENDSESSION` / `WM_ENDSESSION`, **and** its `WM_DESTROY`
teardown performs blocking cross-process cleanup. Both contribute to the
Watson failure
`APPLICATION_HANG_QUIESCE_cfffffff_PowerToys.exe!run_message_loop` on OS
shutdown, sign-out, or restart:

1. Without a `WM_ENDSESSION` handler, `DefWindowProc` returns `0`
without posting a quit message, so `run_message_loop` stays parked in
`GetMessageW` until the OS quiesce timeout (~5 s) force-terminates the
process.
2. Even once teardown starts, `WM_DESTROY` calls
`close_settings_window()`, which blocks up to 1.5 s on
`WaitForSingleObject` against `PowerToys.Settings.exe`
(`src/runner/settings_window.cpp:712`), plus
`Shell_NotifyIcon(NIM_DELETE)` during Explorer teardown. The Windows
[shutdown
guidance](https://learn.microsoft.com/windows/win32/shutdown/shutting-down)
is explicit that handlers must not block.

This PR fixes both issues for the always-on runner. Rollout to
module-owned windows is intentionally separate and tracked in #49539.

> Supersedes #48378 (same Watson bucket) by combining its
no-blocking-cleanup fix with a reusable helper and unit tests. The
cleanup-skip insight is credited to @yeelam-gordon.

Related (same failure class, different binary): #41260.

## Root cause

`src/runner/tray_icon.cpp` → `tray_icon_window_proc` had no case for
`WM_QUERYENDSESSION` / `WM_ENDSESSION`, and `WM_DESTROY` unconditionally
ran cross-process cleanup. On a full Windows session end, the OS
delivers `WM_ENDSESSION` to child applications and reaps them
independently, so the runner's waits consume the quiesce budget without
helping shutdown complete.

## Fix

### 1. Explicitly stateless helper in `src/common/utils/window.h`

`handle_stateless_session_end_message`:

- `WM_QUERYENDSESSION` → returns `TRUE`. The name makes clear that this
helper is only for processes with no unsaved user state.
- `WM_ENDSESSION(TRUE)` → calls `DestroyWindow(window)`, driving the
existing `WM_DESTROY → PostQuitMessage(0)` path so `run_message_loop`
unwinds.
- `WM_ENDSESSION(FALSE)` → leaves the window alone because another
application cancelled shutdown.
- The optional `out_system_session_ending` flag is set only when the
full Windows session is ending. `ENDSESSION_CLOSEAPP` still closes the
runner but leaves the flag false so Restart Manager requests retain
normal child-process cleanup.

Stateful modules must implement their own save/permission behavior
rather than adopt this helper. `tray_icon_window_proc` calls it at the
top of dispatch and returns immediately when the message is handled.

### 2. Skip blocking cleanup only for a full Windows session end

`WM_DESTROY` branches on `g_system_session_ending`:

- **User-initiated close or Restart Manager `ENDSESSION_CLOSEAPP`:**
unchanged full cleanup (`Shell_NotifyIcon(NIM_DELETE)`,
`close_settings_window()`, and `QuickAccessHost::stop()`).
- **Full OS shutdown, sign-out, or restart:** posts `WM_QUIT` without
waiting on child processes the OS is already reaping in parallel.

### Scope and follow-up

This PR intentionally fixes the highest-volume contributor: the
always-on runner. Native module processes with their own windows/message
loops require module-specific review before adopting the pattern; that
inventory and rollout is tracked in #49539.

### Why not centralize handling inside `run_message_loop`?

`WM_QUERYENDSESSION` / `WM_ENDSESSION` invoke the WndProc directly
during `GetMessage`; they do not appear as a `MSG` returned to the loop.
Handling must therefore live in, or be called from, each relevant
WndProc.

## Tests

8 focused tests in `src/common/UnitTests-CommonUtils/Window.Tests.cpp`:

| Test | Guards |
|---|---|
| `HandleStatelessSessionEndMessage_QueryEndSession_AllowsShutdown` |
`WM_QUERYENDSESSION` returns `TRUE`. |
| `HandleStatelessSessionEndMessage_EndSessionCancelled_DoesNotTearDown`
| `WM_ENDSESSION(FALSE)` does not destroy the window. |
|
`HandleStatelessSessionEndMessage_EndSessionConfirmed_TearsDownAndExitsLoop`
| `WM_ENDSESSION(TRUE)` destroys the window and exits before the longer
timer fallback. |
| `HandleStatelessSessionEndMessage_UnrelatedMessage_NotHandled` |
Unrelated messages fall through untouched. |
|
`HandleStatelessSessionEndMessage_EndSessionConfirmed_SignalsSystemSessionEnding`
| A full session end enables the no-wait teardown path. |
|
`HandleStatelessSessionEndMessage_CloseApp_DoesNotSignalSystemSessionEnding`
| Restart Manager closes the window while retaining normal child
cleanup. |
|
`HandleStatelessSessionEndMessage_EndSessionCancelled_DoesNotSignalSystemSessionEnding`
| Cancelled shutdown does not flag teardown. |
|
`HandleStatelessSessionEndMessage_QueryEndSession_DoesNotSignalSystemSessionEnding`
| The query phase does not flag teardown. |

**Build:** `runner.vcxproj` and `UnitTests-CommonUtils.vcxproj` build
clean (`x64|Release`). The 8 focused tests pass.

## Manual validation

1. Build PowerToys and start the runner.
2. Initiate a sign-off (`logoff`) or restart.
3. Confirm Event Viewer (`Windows Logs → Application`) shows no
`Application Hang` event for `PowerToys.exe`.
4. Right-click tray → Exit: confirm Settings.exe and the Quick Access
host shut down gracefully and no ghost tray icon remains.

(#48378 additionally captured real logoff/restart runs showing
`WM_ENDSESSION → WM_DESTROY` completing in 1–8 ms with no hang
events—the same full-session path used here.)

## Quality checklist

- [x] Linked work item: AB#55588441
- [x] Module follow-up: #49539
- [x] Cross-references #41260; supersedes #48378

6d89ade9ad Fix PT Run ThreadPool worker leak from stale query cancellation (#48394)
## Summary

Fixes a ThreadPool worker leak in PowerToys Run that can eventually
surface as `System.OutOfMemoryException` from `Thread.StartInternal`
after rapid typing and repeated stale-query cancellation.

Related: #36041 and duplicate reports #45704, #36587, #39942, #20264,
and #8878.

## Root cause

`MainViewModel.QueryResults` stored the active cancellation token in a
mutable field. When a new query replaced that field, older workers could
observe the new, non-cancelled token instead of the token belonging to
their own query. The previous `CancellationTokenSource` was also
disposed while its consumers could still be running.

As stale queries accumulated, they continued invoking plugins and
consuming ThreadPool workers until the process could no longer create
another worker thread.

## Changes

- Adds `QuerySession`, which owns one captured token and the complete
task lifetime for a query. Superseded sessions are cancelled immediately
and their token sources are disposed only after their work completes.
- Uses a suspended session start so query state is published before
workers can return results.
- Adds generation checks before scheduling and applying work so
superseded queries cannot enqueue stale plugin tasks or update current
results.
- Adds a per-plugin execution gate. Calls to the same plugin do not
overlap, while unrelated plugins can execute independently; cancelled
waiters do not occupy ThreadPool workers.
- Preserves legacy `IResultUpdated` compatibility by correlating
generation-0 events using `RawQuery`.
- Preserves the original two-phase query contract: all non-delayed
plugin queries complete and their results are applied before delayed
queries start. Delayed queries remain globally parallel, and
`noInitialResults` is computed from the complete non-delayed phase.
- Cancels and performs a bounded wait for the active query during
shutdown.

## Tests

`Wox.Test`: **142/142 passing** locally.

Coverage includes:

- token ownership, cancellation, deferred disposal, shutdown timeout,
and suspended session startup;
- current-query generation matching and legacy generation-0
compatibility;
- per-plugin execution gating and queued latest-query behavior;
- deterministic verification that delayed queries cannot start until
every non-delayed query completes.

## Manual validation

1. Hold a key in PowerToys Run for 10–15 seconds and confirm the
PowerToys Run process thread count stabilizes instead of growing
monotonically.
2. Exercise normal Calculator, file, web, and indexer queries.
3. Enable search query tuning and waiting for slow results; confirm
results appear and final sorting completes.
4. Start a slow query and type again before it completes; only the
newest query should update results.
5. Exit PowerToys with a query in flight; shutdown should complete
cleanly without orphaned processes.

44fd627c3a Tighten IContextMenu::GetCommandString in Image Resizer (#48399)
## Summary

Corrects `IContextMenu::GetCommandString` handling in the Image Resizer
shell extension.

## Changes

- `GCS_VERBW` copies the Unicode canonical verb with `StringCchCopyW`,
preserving copy failures.
- Only `GCS_VALIDATEA` and `GCS_VALIDATEW` return `S_OK`.
- ANSI verb requests, help-text requests, and unknown request types
return `E_NOTIMPL`.
- ANSI string verbs are intentionally not advertised because
`InvokeCommand` cannot execute them.
- Updates spell-check expectations for the Windows constants used by
this implementation.

## Validation

The authoritative local versions of all three changed files are pushed
together. A Windows build was not run in this Linux environment.

0d335ffbbd Add Peek.Common unit tests (MathHelper, PathHelper) (#49105)
## Summary

Adds a **Peek.Common.UnitTests** project (MSTest) with unit coverage for
Peek.Common.Helpers:

- **MathHelper.Modulo** — positive/zero results, negative-dividend
wrap-around, large values, and the new non-positive-divisor guard.
- **MathHelper.NumberOfDigits** — single/multi-digit, negative, and 9/10
& 99/100 boundary values.
- **PathHelper.IsUncPath** — standard UNC, subfolders, dotted-server and
IP hosts, plus negatives: drive-letter, relative, empty, HTTP URL,
ile:// URI, single backslash, and null.

Also adds a small correctness guard to MathHelper.Modulo: a non-positive
divisor now throws ArgumentOutOfRangeException instead of silently
throwing DivideByZeroException (b == 0) or returning a misleading result
(b < 0). Registers the test project in `PowerToys.slnx` (ARM64 + x64).

**37 tests pass** locally (x64 Debug).

## Context

This is a clean, **tests-only split of #46684** (the Peek.Common
portion), intentionally **without** the bundled global dependency bump
from that PR. The PowerAccent.Core portion of #46684 was shipped
separately in #49104.

## Test coverage

| Area | Tests |
|------|-------|
| MathHelper.Modulo / NumberOfDigits | included |
| PathHelper.IsUncPath | included |

No production behavior changes beyond the Modulo argument guard, which
is covered by the new tests.

021ca6aee0 Add Runner C++ hotkey conflict unit test seed (#48352)
Adds the C++ counterpart to #48346: a focused Runner native unit-test
seed for core hotkey conflict behavior.

Why this one:
- Runner is core infrastructure rather than another C# module test.
- It adds the missing native C++ test-project path for Runner.
- The seed test is deterministic and covers in-app hotkey conflict
detection.
- It keeps the active rollout to two PRs: one C# module-services PR
(#48346) and one C++ core/runner PR.

Validation:
- `tools\build\build.ps1 -Platform x64 -Configuration Debug -Path
src\runner\UnitTests`
- `vstest.console.exe x64\Debug\tests\Runner\Runner.UnitTests.dll
/Tests:HasConflict_TwoModulesSameHotkey_InAppConflict` → 1 passed

Updates `SharpCompress` from **0.37.2** to **0.50.1** (latest listed
stable) and migrates Peek's `ArchivePreviewer` to the renamed APIs.

0.37.2 is subject to
[GHSA-6c8g-7p36-r338](https://github.com/advisories/GHSA-6c8g-7p36-r338)
(moderate severity), which currently produces an `NU1902` warning on
restore. This upgrade clears it.

The bump also required a real behavioral fix: `.tar.gz` / `.tgz`
previews break outright on 0.50.1 without it. Details below.

## Detailed Description of the Pull Request / Additional comments

Two files change:

**`Directory.Packages.props`** - central version pin moves `0.37.2` to
`0.50.1`. `Peek.FilePreviewer.csproj` needs no edit because its
`PackageReference` is versionless under Central Package Management.


**`src/modules/peek/Peek.FilePreviewer/Previewers/Archives/ArchivePreviewer.cs`**
- the only SharpCompress consumer in the repo.

### API renames

Verified by reflecting over the shipped 0.50.1 assembly rather than
guessing:

| 0.37.2 | 0.50.1 |
|---|---|
| `ArchiveFactory.Open(...)` | `ArchiveFactory.OpenArchive(...)` |
| `ReaderFactory.Open(...)` | `ReaderFactory.OpenReader(...)` |
| `IArchive.TotalUncompressSize` | `IArchive.TotalUncompressedSize` |

`ArchiveEncoding`, `ReaderOptions.Forced`, and
`IEntry.Key`/`Size`/`IsDirectory` are unchanged, so the existing zip
CP437 encoding-probe logic ported over without modification.

### Behavioral fix: `.tar.gz` / `.tgz`

The renames alone are not sufficient. On 0.50.1,
`ArchiveFactory.OpenArchive` can no longer open a gzip-compressed tar as
a random-access archive; it throws `ArchiveOperationException: Cannot
determine compressed stream type`. On 0.37.2 the same call succeeded and
returned `type=Tar`.

I probed six alternatives before settling on a fix: `OpenArchive(path)`,
`ExtensionHint="tar.gz"`, `ExtensionHint=".tar.gz"`,
`LookForHeader=true`, the `FileInfo` overload, and `OpenReader`. Only
`ReaderFactory.OpenReader` works.

The branch is now forward-only through `OpenReader`, and the
`OpenArchive` + `stream.Seek(0)` preamble is removed.

This path is user-reachable, so the break would have shipped:
`FileItem.Extension` returns `.gz` for `foo.tar.gz`, and `.gz` is in
`_supportedFileTypes`, so Peek does preview these files.

### Incidental correctness fix

While rewriting that branch, the reported size changes. The old code
used `archive.TotalUncompressSize`, which for a `.tar.gz` reported the
size of the intermediate **tar container** rather than the sum of the
entries. It now accumulates `reader.Entry.Size`, so the footer
count/size line is correct for these archives.

## Validation Steps Performed

`Peek.FilePreviewer` builds clean (x64 Release) resolving SharpCompress
0.50.1.

Peek has no unit test project, and the only archive coverage in
`Peek.UITests` is `Peek.FilePreview.ZIPArchive`, which previews
`TestAssets\7.zip` and asserts via screenshot comparison. There is no
`.tar.gz` test asset, so nothing in the existing suite would have caught
the regression above.

Given that, I validated with a standalone differential harness that
replicates `LoadPreviewAsync` verbatim and runs it against **both**
0.37.2 and 0.50.1 over the same set of archives, comparing entry names
and sizes:

| Archive | 0.37.2 | 0.50.1 |
|---|---|---|
| `test.zip` | `sub/nested.txt (19)`, `hello.txt (11)`, total 30 |
identical |
| `utf8.zip` | names correct | names correct |
| `sjis.zip` | `日本語/テスト.txt` correct | identical |
| `short.zip` | `caf‚.txt`, `na‹ve.md`, `a¤o.log` (mangled, detected
windows-1252) | `café.txt`, `naïve.md`, `año.log` (correct, detected
utf-8) |
| `test.tar.gz` | opens, total 4096 (container size) | opens, total 30
(correct) |
| `test.tar` | ok | ok |
| `hello.gz` | ok | ok |

All entry names and sizes match. 0.50.1 is strictly more correct on
short non-ASCII entry names and on `.tar.gz` sizing.

One subtle difference worth flagging for reviewers: on `utf8.zip`,
0.50.1 honors `ArchiveEncoding.Forced` even for UTF-8-flagged zips, so
the strict CP437 round-trip no longer throws and `encodingDetermined`
comes back `false` where it was `true` before. The decoded names are
still correct, because charset detection then correctly identifies
UTF-8. No tested case produced wrong output.

Manual validation: previewed `.zip`, `.tar`, `.tar.gz`, and `.gz` files
in Peek.

`NOTICE.md` lists SharpCompress by name without a version, so it needs
no update.

130a77907b [Keyboard Manager] Build the WinUI 3 editor self-contained to fix launch crash (0xC0000409) (#49524)
## Summary of the Pull Request

`PowerToys.KeyboardManagerEditorUI.exe` fail-fasts with `0xC0000409`
(`STATUS_STACK_BUFFER_OVERRUN`) during `MainWindow` construction, so the
new Keyboard Manager editor never opens.
`KeyboardManagerEditorUI.csproj` was the **only WinUI 3 executable in
the repo missing
`<WindowsAppSDKSelfContained>true</WindowsAppSDKSelfContained>`**, so it
was built framework-package-dependent and mixed two Windows App SDK
provenances in one process.

## Detailed Description of the Pull Request / Additional comments

### Root cause

The reporter's WinDbg capture shows a first-chance `Core::ApiException`
carrying `0x800704DF` (`ERROR_ALREADY_INITIALIZED`):

```
MainWindow.SetTitleBar
-> Microsoft.UI.Xaml.Window.set_ExtendsContentIntoTitleBar
-> Microsoft.UI.Input!InputNonClientPointerSourceWinRTStatics::GetForWindowIdHelper
-> Microsoft.UI.Windowing.Core!RegisterWindowFeature
-> Core::NamedApiObject::Init
-> Core::ApiException
```

`ExtendsContentIntoTitleBar` is the **site**, not the cause — it is
simply the first user statement that crosses XAML -> Windowing -> Input.


`microsoft.windowsappsdk.foundation/*/buildTransitive/Microsoft.WindowsAppSDK.BootstrapCommon.targets`
turns the bootstrapper on precisely when this project's shape is hit:

```xml
<PropertyGroup Condition="'$(WindowsAppSdkBootstrapInitialize)'=='' and '$(WindowsAppSDKSelfContained)'!='true' and '$(WindowsPackageType)'=='None' and ('$(OutputType)'=='Exe' or '$(OutputType)'=='Winexe')">
    <WindowsAppSdkBootstrapInitialize>true</WindowsAppSdkBootstrapInitialize>
</PropertyGroup>
```

That compiles in `MddBootstrapAutoInitializer.cs`, which joins the
machine-wide `Microsoft.WindowsAppRuntime` MSIX framework package to the
process package graph before `Main`. Meanwhile the exe's own directory —
`WinUI3Apps` — is first in the Win32 DLL search order and already
contains a complete app-local Windows App SDK payload, deployed there by
the other 14 self-contained apps. One process, two Windows App SDK
provenances, and the one-time feature-type registration in
`Microsoft.UI.Input` collides.

The omission was easy to miss: the project imports
`src\Common.SelfContained.props`, whose name suggests it covers this —
but it only sets the **.NET** `<SelfContained>` property, which is
unrelated.

This also explains why the reporter could not shake it off: the
framework package is machine state, so uninstall/reinstall and wiping
`%LOCALAPPDATA%\Microsoft\PowerToys` change nothing. The classic C++
editor is unaffected because it uses WinUI 2 XAML Islands and ships no
Windows App SDK at all. `PowerToys.Settings.exe` ran healthily in the
same elevated session on the same day while doing strictly more
title-bar work (it sets `ExtendsContentIntoTitleBar` twice and drives
`InputNonClientPointerSource.GetForWindowId` on every `SizeChanged`) —
because it *is* self-contained.

### Two additional defects fixed

Both were found while investigating why the crash left no diagnostics at
all:

1. **`App.xaml.cs` initialized the logger via fire-and-forget
`Task.Run`** — the only one of ~30 `Logger.InitializeLogger` call sites
in the repo to do so. That races window creation, and `Logger` has no
buffering or replay (`Trace.WriteLine` straight through, listener
attached in `InitializeLogger`), so anything logged before the listener
is attached is lost permanently. This is why the user's bug report
bundle contains a `WinUI3Editor` log for the day it worked and **no log
file at all** for the day it crashed. Made synchronous, ordered to match
`FileLocksmithXAML/App.xaml.cs`, plus a log line before the window is
constructed.

2. **`MainWindow` never called
`WindowHelpers.ForceTopBorder1PixelInsetOnWindows10`**, unlike the other
PowerToys WinUI 3 module windows (AdvancedPaste, EnvironmentVariables,
FileLocksmith, Hosts, ImageResizer, Peek, RegistryPreview, Settings). It
is a no-op on Windows 11 and fixes the black top border from
microsoft/microsoft-ui-xaml#6901 on Windows 10 — the OS this issue was
reported against. Happy to drop this hunk if reviewers prefer a minimal
diff.

Deliberately **not** done: wrapping `new MainWindow()` in `try/catch`.
The failure is a WIL `RaiseFailFastException`, which managed code cannot
intercept; and swallowing managed exceptions there would leave a
windowless zombie process still holding the runner's `m_hEditorProcess`
handle, making the runner take its "editor already open" branch and
breaking every subsequent launch. That is why #49477 cannot work.

### Repo-wide audit

All 15 WinUI 3 executables (`UseWinUI=true` and `OutputType=WinExe`)
were checked. **KeyboardManagerEditorUI was the only one missing the
property**; the other 14 already set it. Also verified as correct and
unchanged: the 7 WinUI class libraries (property is app-level, N/A),
`runner.vcxproj` and `PowerRenameUI.vcxproj` (native exes, both already
`true`), and `PowerToys.MeasureToolCore.vcxproj` / `FindMyMouse.vcxproj`
(deliberately `false` — in-proc module DLLs whose host already
establishes the self-contained context).

There is no repo-level default or build guard for this property; it is
hand-copied into 17 project files, which is how the hole opened. A
`Directory.Build.targets` guard that errors when an unpackaged Windows
App SDK executable omits it would prevent recurrence, but it would catch
nothing today, so I left it out of this PR to keep the diff scoped.
Happy to open it separately.

## Validation Steps Performed

Built `KeyboardManagerEditorUI.csproj` (x64/Debug) and diffed the build
output before and after the change:

| | before | after | `PowerToys.Hosts.exe` (reference) |
|---|---|---|---|
| `obj\x64\Debug\Manifests\` (created only by `CreateWinRTRegistration`)
| absent | **present** | present |
| `activatableClass` registrations embedded in the exe | **0** |
**1912** | 1912 |
| assembly references `Microsoft.WindowsAppRuntime.Bootstrap.Net` /
`MddBootstrap` | **yes** | **no** | no |

The editor now resolves every `Microsoft.UI.*` activation app-locally
through registration-free WinRT instead of the machine framework
package, which removes the mixing hazard.

**Not yet validated on Windows 10.** I do not have a Windows 10 19045
machine, so the crash repro itself is unverified end-to-end. The
deployment-mode change is verified from build output as above;
confirmation from the issue reporter would be valuable. A useful
discriminator if anyone has the reporter's ProcDump dump: `lm v m
Microsoft.UI.*` — if `Microsoft.UI.Input.dll` is listed twice from two
different paths, the mechanism is confirmed directly.

7ddfd2f3e0 [Updater] Open PowerToys handle before WM_CLOSE to avoid PID-recycle race (#46973)
Narrows this PR to @yeelam-gordon's review feedback.

The wait-for-exit before launching the installer is **already in
`main`** (landed separately), so the original change here is now
redundant. What's **not** in main is the PID-recycle hazard Gordon
flagged, so this PR applies just that fix:

Open the PowerToys process handle **before** sending `WM_CLOSE`.
PowerToys can exit inside its own `WM_CLOSE` handler, after which the OS
may recycle its PID — opening by PID afterwards could then fail or
attach to an unrelated process that reused it, and `WaitForSingleObject`
would wait on the wrong thing. Holding the handle first anchors the
kernel object to the original process, so PID reuse is impossible while
we wait on it.

Rebased onto latest `main` (resolves the previous merge conflict).

Originally fixes #46966.

page loading.
- Changes window enumeration to refresh asynchronously without blocking
initial results.
- Adds lazy, sequential icon loading with cached icon data.
- Reuses existing list items when window metadata changes.
- Fixes incorrect destruction of borrowed window icon handles.

346b498fb5 Shortcut Guide: Replace dual windows with single transparent overlay and add holding windows button (#48683)
## Summary

Refactors Shortcut Guide from two separate `WindowEx` instances
(`MainWindow` + `TaskbarWindow`) into a single full-monitor transparent
`OverlayWindow` that hosts both surfaces as XAML UserControls. This
enables shared animations and a more polished visual experience, and
makes the taskbar shortcut indicators **edge-aware** for Windows 11's
top/bottom/left/right taskbar positioning.

<img width="507" height="968" alt="image"
src="https://github.com/user-attachments/assets/2e06a3d9-32d9-482e-90fe-1f0f8a7d7598"
/>


## Changes

Closes: #48435
Closes #48491
Closes: #49200
Closes: #48552 (theme flash on Light/System theme + shortcut-list scroll
flutter)
Closes: #48773

### Architecture
- **OverlayWindow**: Single transparent host covering the full monitor
work area, using `TransparentTintBackdrop`
- **MainPaneControl**: The shortcut list pseudo-window, reusing the
shared `TransientSurface` control for chrome (acrylic backdrop, theme
shadow, rounded corners)
- **TaskbarPaneControl + TaskbarIndicator**: Tooltip-style indicators
with triangle tails, positioned above taskbar buttons

### Edge-aware taskbar indicators (Windows 11 top/bottom/left/right)
- Detects the taskbar edge via the public, documented `SHAppBarMessage`
/ `ABM_GETTASKBARPOS` API (the same API CmdPal Dock uses)
- Indicators lay out along the correct axis — horizontally for a
top/bottom taskbar, vertically for a left/right taskbar — with the
triangle tail always pointing toward the taskbar (4-direction tail +
per-edge slide-in animation)
- For a left/right taskbar, the main pane is inset so the order reads
**taskbar | indicators | pane**
- **Adaptive sizing**: each indicator's body size is derived from the
actual measured UIA taskbar button rect, so the bubbles shrink when
Windows uses small icons or combines buttons (many apps open). Uses the
smallest button slot (clamped to a readable range) so neighbouring
bubbles never overlap; the font scales with it

### Visual polish
- Windows 11 system flyout entry/exit animations (slide + fade, ~367ms
entrance / ~200ms exit with cubic easing)
- Animation direction is position-aware (slides from left when
left-aligned, from right when right-aligned)
- Taskbar indicators slide in from the taskbar edge with the same timing
- Close button on the main flyout title bar

### Robustness
- Multi-monitor DPI handling via WM_DPICHANGED suppression (prevents
double-scaling on cross-monitor moves)
- Win11 phantom border elimination (comprehensive DWM/style stripping)
- Click-outside-to-close with animated exit transition
- Process lifetime fix (`Application.Current.Exit()` on close)

## Validation
- Build clean (x64 Debug, exit 0, empty errors log)
- Tested on multi-monitor mixed-DPI setup (150% + 100%)
- Tested with the taskbar docked to each edge (top/bottom/left/right)
and with small/combined taskbar icons

d7afa69048 Fix _snwprintf_s size argument in BugReportTool EventViewer (#48398)
## Summary

Caught while reading through `BugReportTool` for an unrelated review:
the two `_snwprintf_s` calls in `EventViewer.cpp` pass `sizeof(buff)` as
the buffer-size argument, but `buff` is a `wchar_t[1000]`.
`_snwprintf_s` measures its size and count arguments in **wide
characters**, not bytes, so the current code advertises a 2000-wchar
destination for a buffer that only holds 1000.

`cpp
wchar_t buff[1000]; // 2000 bytes, 1000 wchars
memset(buff, 0, sizeof(buff));
_snwprintf_s(buff, sizeof(buff), fmt, ...); // <-- 2000 passed as wchar
count
`

If the formatted output ever exceeds 1000 wchars, the Secure CRT bounds
check fires (in debug) and - depending on which `_snwprintf_s` overload
the compiler selects against the safe template - it can write past the
end of the stack buffer in release. Neither format string here is likely
to produce 1000+ characters in practice (one substitutes a process name,
the other a channel name + integer), so this is more of a latent footgun
than a known crash, but the bounds are simply wrong.

## Fix

Use `_countof(buff)` for the size argument (which is what `_snwprintf_s`
actually wants - element count, not byte count) and pass `_TRUNCATE` for
the count so output is safely capped at 999 wchars plus the null
terminator:

`cpp
_snwprintf_s(buff, _countof(buff), _TRUNCATE, fmt, ...);
`

Applied to both `GetQuery` and `GetQueryByChannel`.

## Scope

Searched the rest of the repo for the same pattern (`_snwprintf_s(buf,
sizeof(...))` / `_snprintf_s(buf, sizeof(...))`) - these two call sites
are the only occurrences in the codebase.

## Validation

- `BugReportTool.sln` rebuilds clean locally (Release|x64) and produces
`PowerToys.BugReportTool.exe`.
- No behavior change on the happy path - both formats are well under
1000 wchars in normal use.

## Risk

Low. Two-line change in a single utility that builds event-log queries
for bug reports. Truncation on overflow is strictly safer than the prior
behavior.
