Why do Windows programs stop responding?

Microsoft WindowsA computer that stops responding or freezes can be caused by many different problems. For example, a software or hardware conflict, lack of system resources, a bug, or other error in the software or drivers can cause a software program, Windows, or the computer to stop responding.

What to do when a program stops responding

To recover, press the Ctrl + Alt + Del keys on your keyboard to open the Close Program or Task Manager window. Once open, highlight the program that is not responding and click the End Task button to terminate the program. If another window opens, click the End Task button again to confirm stopping that program.

Note: If the computer does not respond to Ctrl + Alt + Del, the computer may be deadlocked, and we suggest following the steps for what to do when the computer is completely frozen.

Note: It is important to realize that when a program stops responding, any work that has not been saved will be lost when end tasking a program.

After the program has been end tasked and no longer shows up in the Task Manager, you can try opening the program again to see if it works properly. If you continue to experience issues with that program, restart your computer and then open the program again to see if the issue is now resolved.

If after restarting your computer, the program continues to stop responding make sure there are no available updates or patches for the program are available from the developer that may address the problem.

If no patches are available and the computer is only having problems with one program uninstall the program, restart the computer, and then install the program again to fix any files that may be corrupted or missing that are causing the problem.

If the problems continue to be experienced and it is only happening for one program, we suggest contacting the developer of the program to make sure there are no known issues with the program. If the computer is freezing in multiple programs, you may have a computer problem, and we suggest reviewing our general troubleshooting page for steps that can be performed to help stop this issue from occurring.
