How to End a Program on a PC

Windows

1. 
   Press Alt+Ctrl+Del keys simultaneously, and keep them pressed until you see a window open. This is called the Task Manager.

   • Note: In the new OS, Windows 7, a screen comes up with a number of options. Just click on 'Start Task Manager'.
2. 
   Select the program from the list of open tasks. Also understand that although the name of the task may be unclear, there is also a description column through which you may identify your hanging program.
3. 
   With the unresponsive task highlighted, click on the 'End Process' button at the bottom of the window. When prompted, click 'Yes'.
4. 
   The program is closed. Please note that unsaved changes to most programs will be lost.
