## Detailed Description of the Pull Request / Additional comments
### Known bugs:
- Default settings not saving correctly when switching modes
- Issue: Sometimes when you switch from one mode to another, they are
supposed to update with new defaults but sometimes this fails for the
second variable. Potentially has to do with accessing the settings file
while another chunk of code is still updating.
- Sometimes the system looks "glitched" when switching themes
### To do:
- [x] OOBE page and assets
- [x] Logic to disable the chart when no location has been selected
- [x] Localization
### How to and what to test
Grab the latest installer from the pipeline below for your architecture
and install PowerToys from there.
- Toggle theme shortcutSystem only, Apps only, Both system and apps
selected
- Does changing the values on the settings page update the settings
file? %LOCALAPPDATA%/Microsoft/PowerToys/LightSwitch/settings.json
- Manual mode: System only, Apps only, Both system and apps selected
- Sunrise modes: Are the times accurate?
- If you manage to let this run through sunset/rise does the theme
change?
- Set your theme to change within the next minute using manual mode and
set your device to sleepOpen your device and login once the time you set
has passed. --> Do your settings resync once the next minute ticks after
logging back into your device?
- Disable the service and ensure the tasks actually ends.
- While the module is disabled:
- Make sure the shortcut no longer works
- Make sure the last time you set doesn't trigger a theme change
- Bonus: Toggle GPO Configuration and make sure you are unable to enable
the module
