Task Manager can be used to view and manage your processes, performance statistics, app history, startup apps, users, process details, and services in Windows 11.
Starting with Windows 11 build 22557, Microsoft has updated the design of Task Manager to match the new Windows 11 design principles. This includes a new hamburger style navigation bar and a new settings page. A new command bar on each page gives access to common actions. The dark theme has now been brought to Task manager and will automatically match the system-wide theme configured in the Settings app.
You can turn on Show full account name to display the full account name of signed in accounts listed in the Users tab of Task Manager.
