How to Enable or Disable "Clear Virtual Memory Paging File at Shutdown" in Vista and Windows 7

information   Information
This will show you how to enable or disable clearing the virtual memory pagefile when you restart or shutdown the computer.

By default, this setting is disabled in Vista and Windows 7.
Note   Note

WHY 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.

but how about I'm already turn off the (0) pagefile

please advice,shawn

thanks
 
Hello Darkbluetuber, and welcome to Vista Forums.

Enabling this can only increase the boot time if you restart the computer. When this is enabled, the page file will be cleared at every shutdown and restart adding a bit of time for this to finish first.

This will have no effect when starting the computer when it's already shut down or in sleep mode though.

Hope this helps,
Shawn
