Bugfixes

General

• Fixed an issue which was leading to mouse and keyboard input not working correctly in certain games in builds 25163 and 25169.
• Fixed an issue believed to be leading to SQL Server Management Studio failing to launch.
• Fixed an issue where Memory Integrity in Windows Security may show a warning saying it couldn't be enabled due to incompatible drivers, but the incompatible drivers list would be blank.
• Fixed an issue which was causing some apps to unexpectedly not launch when core isolation was enabled in Windows Security.

File Explorer

• Fixed an issue which could cause explorer.exe to crash when opening new File Explorer windows.
• Fixed an issue where launching File Explorer when using dark mode would unexpectedly show the body of File Explorer in light mode.
• Fixed an issue where the left/right arrows in File Explorer were in light mode when using dark mode, causing them to not have enough contrast to show when they were enabled.
• Fixed an issue where the dividers in the navigation pane were overlapping / drawing too close to text sometimes.
• Fixed an issue where if users drag and drop a folder into the navigation pane was sometimes unexpectedly putting the folder at the bottom of the list rather than where users had dropped it.
• Fixed an issue causing UI issues when using F11 to put File Explorer in full screen mode.

Taskbar

Fixed an issue leading to various system tray elements being unexpectedly missing in build 25169.
