If a program on your computer stops responding, Windows will try to find the problem and fix it automatically. If you don't want to wait, you can end the program yourself by using Task Manager.
Using Task Manager to end a program yourself might be faster than waiting, but any unsaved changes will be lost. If you have important work that you want to keep, wait a few minutes and let Windows try to fix the problem first.
Open Task Manager by right-clicking the taskbar and then clicking Task Manager.
Click the Applications tab, click the program that is not responding, and then click End Task.
