How To Delete Window 2000 and XP Pagefiles

The pagefile can contain unencrypted passwords as well as other sensitive data. While the novice user won't be able to see your pagefile while meandering through your computer, it's still a security risk whenever sensitive information exists on your drive. You can tell your computer to clear your pagefile of any information before it shuts down with a simple registry edit.

The steps:
Go to Start --> Run and type "regedit"
Go to HKEY_LOCAL_MACHINE\ SYSTEM\ CurrentControlSet\ Control\ Session Manager\ Memory Management.

Modify or add the REG_DWORD entry "ClearPageFileAtShutdown" (without the quotes) and set its value equal to 1.

You must restart your computer for the changes to take effect.
