It depends on how fast your computer’s hard drive is and how large your page file is. Your shutdown time may go from a few seconds to a few minutes, or even longer. It will make your computer take much longer to shut down. There’s a real downside to enabling this feature. If someone pulls the hard drive from your computer, they can’t inspect the page file to find any potentially sensitive data that may have been stored in memory. It does this by writing 0’s to every bit of the page file, overwriting any existing data.

If you’re worried about someone snooping for sensitive data that may be left in your page file, Windows can erase it each time you shut down. When you shut down your computer, the system’s RAM is always erased-it’s erased whenever it loses power. RELATED: What Is the Windows Page File, and Should You Disable It?
