The specific method is as follows:
1. First click on the frozen application to be closed, then press Alt+F4 at the same time and keep them after the application is closed;
2. Press Ctrl+Shift+Esc to start the task manager.
Now, although the task manager is open, it will be covered by a full-screen program that is always online.
Then press Alt+O to open the options menu.
Finally, press Enter to select AlwaysonTop.
When you do this, Task Manager keeps your preferences at the top level.
Now, you can use it to terminate a process or application by right-clicking the process and selecting End Task.
If your task manager is set to open in thin mode, press Details to open in detailed mode.
3. If this doesn't work for you, you can use free tools to force the termination of full-screen applications or games.
Win 10 system forced out of the full-screen normally open plan mode, helping everyone to forcibly close the program that the task manager could not terminate. I hope it will help everyone.
