The tried-and-true Task Manager keyboard shortcut continues to function properly in Windows 11. To bring it up, simply press the keys CTRL + SHIFT + ESC on your keyboard at the same time. The window will open right away.

The Start button on your taskbar can be activated by right-clicking it if you do not want to use the keyboard to launch it. Select Task Manager from the menu that displays (which is sometimes referred to as the power users menu), and it will be launched.

Alternatively, you can launch it from the Command Prompt. When the CMD window appears, type taskmgr (for taskmgr.exe, which is the actual application’s filename) on an empty line and press Enter to launch the program. The manager will be launched immediately.

You can also launch the app from the Windows Run box. Press on Windows + R to bring up the Run window, then type taskmgr into the search box, and then press OK or Enter. The Task Manager application will be launched.
