Issues:
Malformed view on scrollling the left sidebar of File Explorer The icons may appear out of place and overlapping text in context menu of File Explorer
Input switcher (WIN + Space) design revert back to an older style and draw in the wrong location. In some cases, the File Explorer context menu no longer has the acrylic effect.

Improvements:

Labels have been added to previously unlabeled actions such as cut, copy, paste, rename, share, and delete
Updated the Task Manager icon to match the design of other icons in Windows 11
