Task Manager Improvements 

We have a set of Task Manager improvements rolling out with this build.  

Filter processes: We are bringing process filtering to Task Manager. This is the top feature request from our users to filter/search for processes. You can filter either 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. This is a helpful feature if you want to single out a process or a group of processes and want to take action or just monitor the performance of the filtered processes. 

The new search box at the top of Task Manager allows you to filter Binary name, PID or Publisher name.

Better theme support: We have added the ability to use your preferred theme in Task Manager regardless of the active theme in Windows. You can set it in the setting page in Task Manager.  

You can set your preferred theme specifically for Task Manager regardless of your chosen Windows theme.

Task Manager now also supports themes for in-app dialogs. All dialog except for “Run new task” and Properties dialog now support themes and will adhere to either app specific theme or Windows theme.   

In-app dialogs such as selecting columns on the Details page will show in the selected theme for Task Manager.

Improved Efficiency mode dialog: We are making it easy for you to apply Efficiency mode and offering the ability to opt-out of the confirmation dialog. You can make changes on the Efficiency mode dialog box by unchecking “Don’t ask me again” or you can enable/disable it the settings for Task Manager. 

You can now opt out of seeing future confirmation dialogs when turning on Efficiency mode.

FEEDBACK: Please file feedback in Feedback Hub (WIN + F) under Desktop Environment > Task Manager.
