Changes[edit | edit source]
- If the users's download folder is synced to a cloud provider, it disables the option to have Storage Sense automatically clear your Downloads folder on a cycle.
- Login logic was updated, so if the user has their PC set up so they have to type their username while logging in, typing a space at the beginning of your username will not generate an error anymore.
Bugs and quirks[edit | edit source]
- Some devices have a chance of crashing with a BSOD upon resuming from hibernate if booting from eMMC storage.
- The update process to this build has a chance of hanging for extended periods of time.
- Both the documents and downloads sections in the privacy settings have broken icons, and as such, rectangles show up where the icons are intended to be instead.
- Taskbar preview thumbnails sometimes do not render consistently. If this happens, a blank area will be shown instead of the thumbnail.
