This article 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.
Some third-party programs may temporarily store unencrypted (plain-text) passwords or other sensitive information in memory. Because of Windows virtual memory architecture, this information may be present in the paging file.
Although clearing the paging file is not a suitable substitute for physical security of a computer, you may want to increase the security of data on a computer while Windows is not running.
