How To Clear The Windows Paging File At Shutdown For XP

For Microsoft Windows 2000 Method
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system.
Description of the Microsoft Windows Registry
This documents the method for clearing the Windows paging file (Pagefile.sys) during the shutdown process, so that no unsecured data is contained in the paging file when the shutdown process is complete.
If you enable this feature, the shutdown time may be increased.
Some third-party programs can temporarily store unencrypted (plain-text) passwords or other sensitive information in memory. Because of the Windows virtual memory architecture, this information can be present in the paging file.
Although clearing the paging file is not a suitable substitute for physical security of a computer, you might want to do this to increase the security of data on a computer while Windows is not running.
1. Start Registry Editor (Regedt32.exe).
2. Change the data value of the ClearPageFileAtShutdown value in the following registry key to a value of 1:
3. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management
If the value does not exist, add the following value
Value Name: ClearPageFileAtShutdown
Value Type: REG_DWORD
Value: 1
This change does not take effect until you restart the computer.
