If you ever want to quickly Shut Down or Restart Windows XP, you can use Alt + F4 do get the job done. Alt + F4 is usually the “Exit” keyboard shortcut to exit the current program. However, if you’re on your Desktop, hitting Alt + F4 will actually prompt you to Stand By, Turn Off, or Restart your computer. Say, you have a program running and want to Restart, just hit the Windows Key + D (to go to the Desktop), then hit Alt + F4 to launch the prompt.
