Why do Windows programs stop responding?
A computer that stops responding can be caused by many different problems. For example, a confliction between software or hardware, lack of system resources, or a bug in the software or drivers can all cause a 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: 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.
