Miscellaneous
The underlying speech platform has been updated to improve voice activity detection for voice access, live captions, and voice typing, as well as address some issues with how punctuation is recognized.

Shell

 * Fixed an issue leading to users encountering the  error when copying files from Google Drive.
 * Fixed an issue where if users had ever opened the context menu, doing Ctrl and cancelling would lead to  crashing.
 * Fixed an issue related to loading the system tray icons under the Taskbar page in the Settings app which could cause it to crash when opening that page recently.

Windows Security
Fixed an issue which could result in Smart App Control unexpectedly blocking correctly signed applications.

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.
