## Summary of the Pull Request
Window Walker's fuzzy string matching algorithm exhibits exponential
memory usage and execution time when given inputs containing repeated
characters or phrases. When a user has several windows open with long
titles (such as browser windows), it is straightforward to trigger a
pathological case which uses up gigabytes of memory and freezes the UI.
This is exacerbated by Run's lack of thread pruning, meaning work
triggered by older keystrokes consumes CPU and memory until completion.

## Detailed Description of the Pull Request / Additional comments
The existing algorithm in `FuzzyMatching.cs` is greedy, creating all
possible matching combinations of the search string within the candidate
via its `GetAllMatchIndexes()` method. After this, it selects the best
match and discards the others. This may be considered reasonable for
small search strings, but it causes a combinatorial explosion when there
are multiple possible matches where characters or substrings repeat,
even when the search string is small.
The current brute-force algorithm has time complexity of **O(n * m *
C(n,m))** where **C(n,m)** = **n!/(m!(n-m)!)** and space complexity of
**O(C(n,m) * m)** because it stores all possible match combinations
before choosing the best.
For example, matching `"eeee"` in `"eeeeeeee"` creates **C(8,4)** =
**70** match combinations, which stores 70 lists with 4 integers each,
plus overhead from the LINQ-based list copying and appending:
```csharp
var tempList = results
.Where(x => x.Count == secondIndex && x[x.Count - 1] < firstIndex)
.Select(x => x.ToList()) // Creates a full copy of each matching path
.ToList(); // Materializes all copies
results.AddRange(tempList); // Adds lists to results
```
Each potential sub-match may be recalculated many times.
Window Walker queries across all window titles, so this problem will be
magnified if the search text happens to match multiple titles and/or if
a search string containing a single repeated character is used. For
browser windows, where titles may be long, this is especially
problematic, and similarly for Explorer windows with longer paths.
## Proposed solution
The solution presented here is to use a dynamic programming algorithm
which finds the optimal match directly without generating all
possibilities.
In terms of complexity, the new algorithm benefits from a single pass
through its DP table and only has to store two integer arrays which are
sized proportionally to the search and candidate text string lengths; so
**O(n * m)** for both time and space, i.e. polynomial instead of
exponential.
Scoring is equivalent between the old and new algorithms, based strictly
on the minimum match span within the candidate string.
## Implementation notes
The new algorithm tracks the best start index for matches ending at each
position, eliminating the need to store all possible paths. By storing
the "latest best match so far" as you scan through the search text, you
are guaranteed to minimise the span length. To recreate the best match,
a separate table of parent indexes is kept and iterated backwards once
the DP step is complete. Reversing this provides you with the same
result (or equivalent if there are multiple best matches) as the
original algorithm.
For this "minimum-span" fuzzy matching method, this should be optimal as
it only scans once and storage is proportional to the search and
candidate strings only.

(Where "Old_Explosion" is "e" repeated 9 times. Times in nanoseconds or
one millionth of a millisecond.)
It is worth noting that the results show a **single string match**. So
matching "eeeeee" against a 99-character string took 25 MB of memory and
71 milliseconds to compute. For the new algorithm, this is reduced down
to <5KB and 0.002 milliseconds. Even for a three-character repetition,
the new algorithm is >150x faster with <1% of the allocations.

/>
## Validation Steps Performed
The verification tests in the benchmark project pass, with results
identical to the original across a number of test cases, including the
pathological cases identified earlier and edge cases such as
single-character searches.
All unit tests under `Wox.Test`, including all 38 `FuzzyMatcherTest`
entries still pass.
## Summary of the Pull Request
This fixes a race condition in the WindowWalker component in both
**Command Palette** and **Run**. The lack of a lock around a cache
update could potentially lead to inaccurate information about UWP
applications being returned.

## Detailed Description of the Pull Request / Additional comments
More details about the root cause can be found in the original issue:
#45600.
In summary, a `Task` is created and started as part of the
`CreateWindowProcessInstance()` code. The creation is inside a lock, but
there is no lock around access to the `_handlesToProcessCache` cache
within the Task itself, which will run on a different thread.

## Detailed Description of the Pull Request / Additional comments
**Build System & Configuration:**
- Updated `Cpp.Build.props` to use `v145` (VS 2026) as the default
`PlatformToolset`, with fall back to `v143` for VS 2022.
- Configured C++ Language Standard:
- `stdcpplatest` for production projects.
- Removed explicit `<PlatformToolset>` definitions from individual
project files (approx. 37 modules) to inherit correctly from the central
`Cpp.Build.props`.
**Code Refactoring & Fixes:**
- Updated `DrawingHelperTests.cs` in MouseJump Unit Test to ease the
pixel difference tolerance. This became an issue after switching to the
new VS2026 build agent.
<!-- Describe how you validated the behavior. Add automated tests
wherever possible, but list manual validation steps taken as well -->
## Validation Steps Performed
- Validated successful compilation of the entire solution. Similar
updates have been made to the .NET 10 branch, but these are much cleaner
and will be merged into that branch once fully confirmed working.

## Summary of the Pull Request
This PR expands the scenarios where Run handles exceptions silently,
reducing the number of exception dialogs displayed to users and creating
a smoother experience. The premise remains unchanged: most exceptions
occur when Run is in the background, and the app can recover as the DWM
recovers.
This should cover most of the reports commonly encountered in the wild.
- Extended silent handling of DWM exceptions to include
`DWM_E_COMPOSITIONDISABLED` (0x80263001).
- Added silent handling for `STATUS_MESSAGE_LOST` error (NTSTATUS
0xC0000701, HR 0xD0000701).
- Implemented exception handling and retry logic for failures during
manual app theme changes (triggered by
`PowerLauncher.Helper.ThemeManager`).
I can't reproduce the error on its own; it only occurs alongside a fatal
render thread failure (`UCEERR_RENDERTHREADFAILURE`), which is
unrecoverable. Even if caught, the UI stops rendering, leaving the
end-user unable to proceed.

## Validation Steps Performed
### NuGet Package Management Improvements:
* This pull request includes updates to improve NuGet package management
and dependency versions.
### Example problem of the new ps1 change, and fixed in this PR
Updated the version of `NLog` from `5.0.4` to `5.2.8`, with the error
message:
error NU1605:
Warning As Error: Detected package downgrade: NLog from 5.2.8 to 5.0.4.
Reference the package directly from the pr
oject to select a different version.
Microsoft.PowerToys.Run.Plugin.History -> Wox.Plugin ->
NLog.Extensions.Logging 5.3.8 -> NLog (>= 5.2.8)
Microsoft.PowerToys.Run.Plugin.History -> Wox.Plugin -> NLog (>= 5.0.4)
The test
`Win32ProgramRepositoryMustCallOnAppRenamedForLnkAppsWhenRenamedEventIsRaised`
was experiencing random failures due to object identity mismatches in
the repository's hash-based storage system.
## Root Cause
The test was manually creating `Win32Program` objects:
```csharp
Win32Program olditem = new Win32Program
{
Name = "oldpath",
ExecutableName = oldpath,
FullPath = linkingTo,
};
```
However, the `DoOnAppRenamedAsync` method creates the `oldApp` object
for removal using a different approach for .lnk files:
```csharp
oldApp = new Win32Program() {
Name = Path.GetFileNameWithoutExtension(e.OldName),
ExecutableName = Path.GetFileName(e.OldName),
FullPath = newApp?.FullPath ?? oldPath
};
```
Since the repository uses `GetHashCode()` (based on `Name`,
`ExecutableName`, and `FullPath`) to identify objects for removal, any
subtle differences in these properties would cause the `Remove()`
operation to fail, leading to test assertion failures.
## Fix
Changed the test to use `Win32Program.GetAppFromPath()` instead of
manual object creation:
```csharp
Win32Program olditem = Win32Program.GetAppFromPath(oldFullPath);
Win32Program newitem = Win32Program.GetAppFromPath(newFullPath);
```
This mirrors the approach used in the working
`Win32ProgramRepositoryMustCallOnAppRenamedForUrlAppsWhenRenamedEventIsRaised`
test and ensures that test objects are created using the same code path
as the production code, eliminating hash code mismatches.
## Why This Was Random
The test failure appeared random because it depended on subtle
differences in object creation that could vary based on timing, mock
setup, or other environmental factors. By using the same object creation
method as the production code, the test becomes deterministic.

## Summary of the Pull Request
Telemetry.write will serialize all of the whole object graph. So we need
to ensure it will not be trimmed.
This is a safe PR because it doesn't apply any logic change. If you
disable the AOT feature, this PR won't take any effect.

## Summary of the Pull Request
This actually fixes an issue with #39794. What I failed to mention in
the original issue was the additional path under the registry that the
new key is located under. Instead of the key being stored directly in
`UserChoiceLatest` in a key named `ProgId`, the path also includes a
second `ProgId` as well.
Copilot tried to fix this issue in #40035, but because I had failed to
mention the additional `ProgId` in the path, it was not included in
Copilot's fix.
Therefore, the true new path is
`.../UserChoiceLatest/ProgId`

## Summary
This PR fixes an issue where PowerToys Web Search and PowerToys Run
would always open Microsoft Edge instead of the user's default browser
on Windows 11 24H2, even when a different browser like Firefox was set
as the default.
## Root Cause
Windows 11 24H2 introduced a change where default browser associations
are now stored in a new registry location:
- **New location**:
`HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\http\UserChoiceLatest`
- **Old location**:
`HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\http\UserChoice`
PowerToys was only checking the old registry location, causing it to
fail to find the default browser and fall back to Microsoft Edge.
## Changes Made
Updated both `DefaultBrowserInfo.cs` files to check the new registry
location first, then fall back to the old location for backward
compatibility:
1. **Command Palette Web Search**:
`src/modules/cmdpal/ext/Microsoft.CmdPal.Ext.WebSearch/Helpers/DefaultBrowserInfo.cs`
2. **PowerToys Run**:
`src/modules/launcher/Wox.Plugin/Common/DefaultBrowserInfo.cs`
**Before**:
```csharp
var progId = GetRegistryValue(
@"HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\http\UserChoice",
"ProgId");
```
**After**:
```csharp
var progId = GetRegistryValue(
@"HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\http\UserChoiceLatest",
"ProgId")
?? GetRegistryValue(
@"HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\http\UserChoice",
"ProgId");
```
## Testing
- Verified the fallback logic works correctly with a test application
- Confirmed both affected files are updated with the same pattern
- Ensured backward compatibility with older Windows versions
## Impact
This fix ensures that:
- Users on Windows 11 24H2 will have their default browser respected
- Older Windows versions continue to work as before
- No breaking changes are introduced
Fixes#39794.

## Summary of the Pull Request
This PR updates all application manifest files across the PowerToys
codebase to use **PerMonitorV2** DPI awareness, ensuring optimal
high-DPI display support on modern Windows systems.
## Changes Made
Updated **12 manifest files** to include proper PerMonitorV2 DPI
awareness:
### Files with New DPI Support Added:
- `src/runner/PowerToys.exe.manifest` - Added complete DPI awareness
section
- `src/modules/awake/Awake/app.manifest` - Upgraded from basic
`dpiAware` to PerMonitorV2
### Files Upgraded from PerMonitor to PerMonitorV2:
- `src/modules/colorPicker/ColorPickerUI/App.manifest`
- `src/modules/MouseWithoutBorders/App/MouseWithoutBorders.exe.manifest`
### Files Enhanced for Consistency:
- `src/modules/ShortcutGuide/ShortcutGuide/ShortcutGuide.exe.manifest`
- `src/modules/ZoomIt/ZoomIt/Zoomit.exe.manifest`
- All 5 cmdpal extension manifests
## Technical Implementation
All manifests now use the standardized format that provides:
1. **PerMonitorV2** as the primary DPI awareness mode for Windows 10
Anniversary Update and later
3. **`true/PM`** for backward compatibility with pre-Windows 10 systems
```xml
<application xmlns="urn:schemas-microsoft-com:asm.v3">
<windowsSettings>
<dpiAware xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">true/PM</dpiAware>
<dpiAwareness xmlns="http://schemas.microsoft.com/SMI/2016/WindowsSettings">PerMonitorV2, PerMonitor</dpiAwareness>
</windowsSettings>
</application>
```

## Summary of the Pull Request
Problem
-------------
We've observed multiple bug reports related to crashes with the
following exceptions:
System.Runtime.InteropServices.COMException (0xD0000701)
System.Runtime.InteropServices.COMException (0x80263001)
The root cause of these crashes has been traced to the WPF framework,
specifically this line in WindowChromeWorker.cs:
3439f20fb8/src/Microsoft.DotNet.Wpf/src/PresentationFramework/System/Windows/Shell/WindowChromeWorker.cs (L1005)
These crashes are not necessarily caused by PowerToys Run itself being
used, or even visible. However, users perceive them as Run-related
because the "Report problem UI" is triggered by our global exception
handler, surfacing the underlying WPF crash.
Fix
------------
This PR:
- Suppresses the launch of the "Report problem UI" for exceptions known
to be triggered by unstable platform conditions (such as COMExceptions
from WPF internals).
- Continues to log the exception to preserve diagnostic data.
This change ensures we:
- Avoid showing an UI when WPF framework itself is already having
problem to handling DWM composition changes.

In CmdPal and PT Run, if you currently try to go to mouse pointer, it fails. This looks to be due to capitalization in the command. This can be validated via run dialog also.
shifting to lowercase fixes the bug.
