Shell
The unified hitboxes for Win32 system tray icons and the "show hidden icons" flyout, which initially announced in build 22563 and later rolled out to all users in build 22581, have been reverted to address feedback. As part of this change, the drag-and-drop feature for pinning or unpinning the tray icons has been re-enabled.

Input
Fixed an issue which was leading to some apps crashing when pressing the half-width/full-width key while using the Japanese IME.

Widgets

 * Fixed an issue causing the Widgets board to open and then immediately close if users tried to open the widgets board using a gesture from the side of the screen.
 * Fixed an issue where users were unable to use the swipe functionality to reliably invoke Widgets.

Task Manager
Fixed an issue that was causing the process list to fluctuate between Apps & Background groups when clicking on Efficiency mode from the command bar.

Live captions

 * Certain apps in full screen (e.g., video players) may prevent live captions from being visible.
 * Certain apps positioned near the top of the screen and closed before live captions is run may re-launch behind the live captions window positioned at top.

Safe mode

 * Quick Settings and date/time clock on the taskbar may be missing due to the  service not running.
 * Clicking Bluetooth & devices and Personalization pages may crash the Settings app due to an overrun of a stack-based buffer.
