These are the new features and improvements expected to arrive in the next feature drop of Windows 11:

Task Manager

On build 22623.891, Windows 11 rolls out an updated version of Task Manager with a new filter feature to search processes using the binary name, PID, or publisher name. 

The filter algorithm matches the context keyword with all possible matches and displays them on the current page. The filter is also applied as you switch between pages. You can also use the keyboard shortcut “ALT + F” to focus on the filter box.

Microsoft is also improving the theming experience with a new option that allows you to change the color mode regardless of the system color mode you use.

In addition, Task Manager now supports themes for in-app dialogs. All dialog except for the “Run new task” and “Properties” dialog now supports themes.   

Finally, this version of the app makes it easy to apply efficiency mode and offers the ability to opt out of the confirmation dialog. You can change the “Efficiency mode” dialog box by unchecking “Don’t ask me again,” or you can disable it from the Task Manager settings.

  • You can back up applicable settings to your Microsoft account. You can also sync these settings on any Windows device and in Microsoft Office.

  • Fixed an issue that affected the CopyFile function. It might have sometimes returned error 317: ERROR_MR_MID_NOT_FOUND.  
  • Fixed an issue that affected process creation. It failed to create security audits for it and other related audit events. 
  • Fixed an issue that affected printing in landscape mode in Microsoft Edge. The print output was incorrect. This issue occurred when you used Microsoft Defender Application Guard.
  • Fixed an issue that affected Microsoft Defender when it was not the primary antivirus. Microsoft Defender failed to turn off passive mode. This issue occurs when you turn off Smart App Control (SAC). 
  • Added .wcx to the list of Dangerous Extensions that some app control policies do not allow. 
  • Fixed an issue that affected a computer account. The use of non-standard characters can stop the cleanup of the Out of Box Experience (OOBE) accounts.

  • Fixed an issue that might have affected applications that run on the Windows Lock Down Policy (WLDP). They might have stopped working. 

Microsoft is looking into problems with the Taskbar and Task Manager as part of the known issues.
