In the following paragraphs, we are going to walk you through the new changes and improvements in KB5052090.
1. Lock Screen Widgets
Microsoft said Windows Insiders in the European Economic Area (EEA) are experiencing their lock screen widgets. It allows users to add, remove or rearrange lock screen widgets such as weather, watchlist, sports, traffic, and more. Any widget that supports the small sizing option can be added here.

There is also a new group policy called Disable Widgets On Lock Screen that allows you to disable lock screen widgets without affecting widgets elsewhere on PCs you manage. To customize it, press Win + R to open the Run box > enter gpedit >hit OK to launch Group Policy Editor > navigate to Computer Configuration > Administrative Templates > Windows Components > Widgets.
2. Task Manager Improvements
Microsoft is modifying the way Task Manager calculates CPU utilization in the Processes, Performance and Users pages. An option CPU utility hidden by default is added on the Details tab so as to show the previous CPU value used on the Processes page.
3. Windows Share
After installing the KB5052090, you are able to share directly with Windows programs that support the sharing function by right-clicking on your local files in File Explorer or Desktop.

4. Bugs Fixes
- Fixed an issue where File Explorer Home might not load correctly and just show random floating text saying Name.
