## Summary of the Pull Request
This PR updates the PowerToys solution to support **Visual Studio 2026
(PlatformToolset v145)**. It centralizes the build configuration,
updates the C++ language standards, and fixes an issue with a MouseJump
unit test that appears while using the VS 2026 supported build agent.

## 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.

This PR contains a set of bug fixes and general improvements to
[Awake](https://awake.den.dev/) and developer experience tooling for
building the module.
### Awake Fixes
- **#32544** - Fixed an issue where Awake settings became non-functional
after the PC wakes from sleep. Added `WM_POWERBROADCAST` handling to
detect system resume events (`PBT_APMRESUMEAUTOMATIC`,
`PBT_APMRESUMESUSPEND`) and re-apply `SetThreadExecutionState` to
restore the awake state.
- **#36150** - Fixed an issue where Awake would not prevent sleep when
AC power is connected. Added `PBT_APMPOWERSTATUSCHANGE` handling to
re-apply `SetThreadExecutionState` when the power source changes
(AC/battery transitions).
- **#41674** - Fixed silent failure when `SetThreadExecutionState`
fails. The monitor thread now handles the return value, logs an error,
and reverts to passive mode with updated tray icon.
- **#41738** - Fixed `--display-on` CLI flag default from `true` to
`false` to align with documentation and PowerToys settings behavior.
This is a breaking change for scripts relying on the undocumented
default.
- **#41918** - Fixed `WM_COMMAND` message processing flaw in
`TrayHelper.WndProc` that incorrectly compared enum values against enum
count. Added proper bounds checking for custom tray time entries.
- **#44134** - Documented that `ES_DISPLAY_REQUIRED` (used when "Keep
display on" is enabled) blocks Task Scheduler idle detection, preventing
scheduled maintenance tasks like SSD TRIM. Workaround: disable "Keep
display on" or manually run `Optimize-Volume -DriveLetter C -ReTrim`.
- **#38770** - Fixed tray icon failing to appear after Windows updates.
Increased retry attempts and delays for icon Add operations (10
attempts, up to ~15.5 seconds total) while keeping existing fast retry
behavior for Update/Delete operations.
- **#40501** - Fixed tray icon not disappearing when Awake is disabled.
The `SetShellIcon` function was incorrectly requiring an icon for Delete
operations, causing the `NIM_DELETE` message to never be sent.
- Fixed an issue where toggling "Keep screen on" during an active timed
session would disrupt the countdown timer. The display setting now
updates directly without restarting the timer, preserving the exact
remaining time.
### Performance Optimizations
- Fixed O(n²) loop in `TrayHelper.CreateAwakeTimeSubMenu` by replacing
`ElementAt(i)` with `foreach` iteration.
- Fixed Observable subscription leak in `Manager.cs` by storing
`IDisposable` and disposing in `CancelExistingThread()`. Also removed
dead `_tokenSource` code that was no longer used.
- Reduced allocations in `SingleThreadSynchronizationContext` by
changing `Tuple<>` to `ValueTuple`.
- Replaced dedicated exit event thread with
`ThreadPool.RegisterWaitForSingleObject()` to reduce resource usage.
### Code Quality
- Replaced `Console.WriteLine` with `Logger.LogError` in `TrayHelper.cs`
for consistent logging.
- Added proper error logging to silent exception catches in
`AwakeService.cs`.
- Removed dead `Math.Min(minutes, int.MaxValue)` code where `minutes` is
already an `int`.
- Extracted hardcoded tray icon ID to named constant `TrayIconId`.
- Standardized null coalescing for `GetSettings<AwakeSettings>()` calls
across all files.
### Debugging Experience Fixes
- Fixed first-chance exceptions in `settings_window.cpp` during
debugging. Added `HasKey()` check before accessing `hotkey_changed`
property to prevent `hresult_error` exceptions when the property doesn't
exist in module settings.
- Fixed first-chance exceptions in FindMyMouse `parse_settings` during
debugging. Refactored to extract the properties object once and added
`HasKey()` checks before all `GetNamedObject()` calls. This prevents
`winrt::hresult_error` exceptions when optional settings keys (like
legacy `overlay_opacity`) don't exist, improving the debugging
experience by eliminating spurious exception breaks.
- Fixed LightSwitch.UITests build failures when building from a clean
state. Added missing project references (`ManagedCommon`,
`LightSwitchModuleInterface`) with `ReferenceOutputAssembly=false` to
ensure proper build ordering, and added existence check for the native
DLL copy operation.
### Developer Experience
- Added `setup-dev-environment.ps1` script to automate development
environment setup.
- Added `clean-artifacts.ps1` script to resolve build errors from
corrupted build state or missing image files.
- Added build script that allows standalone command line build of the
Awake module.
- Added troubleshooting section to
`doc/devdocs/development/debugging.md` with guidance on resolving common
build errors.
Closes#37100
