Let us say that you have a Program or a Game open in full-screen always-on-top mode, where even your Taskbar is not visible, and the application freezes, and you find yourself in a position where there is seemingly nothing you can do except restarting your Windows 11/10 computer. What can you do?

- Open Task Manager in a Virtual Desktop
- Use Command Line
- Use a free tool.
How to exit Full Screen on Windows 11

1] Use Alt+F4 keys
First, click on the frozen application you want to close and then press the Alt+F4 keys together and leave them after the application closes. Does this help?
2] Use Ctrl+Shift+Esc and then Alt+O
To force quit a Full-Screen Always-On-Top Program in Windows 11/10:
- Press Ctrl+Shift+Esc to launch the Task Manager.
- Now although the Task Manager opens it will be covered by the always-on-top full-screen program.
- Next press Alt+O to open the Options menu.
- Finally, press Enter to select Always on Top.
- When you do this, the Task Manager will get the preference to stay on the top.
- You will now be able to use it to kill the process or application by right-clicking on the process and selecting End task.
If your Task Manager is set to open in the Compact Mode, press More details to open it in Details Mode.
3] Open Task Manager in a Virtual Desktop
If the game keeps covering Task Manager:
- Press Win+Tab.
- Click New Desktop.
- Open Task Manager there.
- End the frozen application.
4] Use Command Line
Press Win+R to open the Run box. Type this command and hit Enter.
taskkill /f /im game.exe
Here, replace game.exe with the actual name of your game.
5] Use a free tool
If this does not work for you, you can use a free tool to forcefully terminate a full-screen application or game.
