Microsoft is testing a new search and filter system for Task Manager on Windows 11 allowing users to easily find a misbehaving app

Microsoft has announced the availability of Windows 11 Insider Preview Build 22621.891 and 22623.891 in the beta channel.

Task manager improvements

Microsoft has highlighted the arrival of a set of task manager enhancements rolled out with this release.

Filter processes*: Microsoft brings process filtering to Task Manager. This is the main feature request from users to filter/search for processes. You can filter using binary name, PID or publisher name. The filtering algorithm matches the context keyword with all possible matches and displays them on the current page. The filter is also applied when you move from one page to another. You can also use the keyboard shortcut ALT+F to focus on the filter area. This is a useful feature if you want to isolate a process or a group of processes and want to take action or just monitor the performance of the filtered processes.

Better theme support: Microsoft has added the ability to use your favorite theme in Task Manager, regardless of which theme is active in Windows. You can set it in the Task Manager configuration page

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

Enhanced Efficiency Mode dialog box*: Microsoft has made it easier to apply Efficiency Mode and gives you the option to disable the confirmation dialog. You can make changes in the Efficiency mode dialog box by unchecking Don’t ask me again or you can enable/disable Task Manager settings.

Fixes in build 22623.891:
