Backup and Restore Improvements

You should always back up your Windows 11 PC before installing any new software, in case the new program causes problems and you need to roll back to an earlier point in time. With this release, you may now import your previous Windows PC’s settings and restore your pinned apps with the new Windows backup program.


Dynamic Lighting

You may control the RGB of all your external devices that are hooked up to your Windows 11 PC with the help of Dynamic Lighting. This frees you from the need to utilize separate software to customize the RGB lighting effects of your keyboard, mouse, cabinet fans, and anything else that supports it. Microsoft is collaborating with numerous original equipment manufacturers and original design manufacturers to have this functionality pre-installed in Windows 11.

We should expect to see more Rust implementation in future Windows 11 updates now that the win32base_rs.sys code is included in the current update. At this time, only a select group of Insiders on the Canary Channel can get the update.

Arm32 UWMP Apps Lose Support
