Required XP Processes

These are the processes that must be running for Windows to function properly. Killing any of these will stop Windows from working correctly. Any other process is fair game, however.

• explorer.exe (not to be confused with Internet Explorer's iexplore.exe)
• csrss.exe
• lsass.exe
• services.exe
• smss.exe
• winlogon.exe
• alg.exe (added in Service Pack 2)
• svchost.exe (depending on your configuration, your computer may have between 4 and 6 copies of this running at the same time)
