Apart from Hibernate feature, Microsoft also offers Paging File (pagefile.sys) in Windows 10/8/7 to gear up or speed up Windows PC. A paging file, also known as a page file, is an additional virtual memory when your RAM fills up.
Whenever you shut down your computer or power losses, the system’s RAM is always erased; however, the page file isn’t. If you are working with some sensitive data and you’re worried about someone snooping for sensitive data that may be left in your page file, you can configure your Windows PC to erase it each time you shut down. Once you erase the page file and someone pulls the hard drive from your computer, they can’t examine the page file to find any potentially sensitive data that may have been stored in memory.
If you are not working with any sensitive data on your PC, it is not good for you to erase the page file at the PC’s shutdown. It is not recommended to erase the page file at shutdown as it will make your computer take much longer to shut down. Your shutdown time may go from a few seconds to a few minutes or even higher. It totally depends on how fast your computer’s hard drive is and how large your page file is. This is the actual reason Windows doesn’t automatically clear the page file at shutdown by default.
This post will guide you on automatically erasing the Windows Paging File at Shutdown in Windows 10/8/7. There are at least two methods through which you can erase the Windows Paging File at PC Shutdown; these are the following:-
