By default, this setting is disabled in Vista and Windows 7.
NoteWHY ENABLE:
Sensitive information may have been temporarily stored in the virtual memory pagefile. For this security reason and others, it may be a good idea to enable this setting to clear the virtual memory pagefile occasionally or when you suspect this. When this setting is enabled it will clear the virtual memory pagefile, and the hibernation file only on a portable computer, when you restart or shutdown the computer.
WHY DISABLE:
When this setting is enabled it can add around a minute or so to how long it takes your computer to shutdown and restart. How much time it will add depends on how much RAM you have installed and how big the Virtual Memory Paging File is set at.
