When an app stops responding in Windows 11, try closing it normally before forcing it to quit so the program has a chance to save data.
Steps
- Click the app’s Close button or press Alt+F4 first.
- If it does not respond, press Ctrl+Shift+Esc to open Task Manager.
- Select the frozen application under Processes.
- Choose End task.
- Reopen the app and check for document recovery, updates, or a repeatable cause of the freeze.
How it works
Ending a task terminates the process without normal shutdown, so unsaved changes can be lost. Some applications have helper/background processes; ending the visible app may not stop every related service.
Important considerations
Do not end unfamiliar Windows system processes at random. If the whole PC is frozen, wait briefly for disk/update activity before resorting to a forced power-off.
Practical guidance
If Task Manager itself will not open, Ctrl+Alt+Delete can provide access to Task Manager or sign-out/restart controls. `taskkill` is available for advanced command-line termination when you know the exact process, but Task Manager is safer for ordinary troubleshooting. Repeated freezes warrant application logs/updates or hardware checks.
Additional details
Before force quitting a document editor, wait a moment and check whether Windows labels it Not responding during a long save/export. Killing it mid-write can corrupt the output. After reopening, use the application’s recovery feature and save recovered work under a new filename before continuing.
