Support for Windows Vista Service Pack 1 (SP1) ends on July 12, 2011. To continue receiving security updates for Windows, make sure you're running Windows Vista with Service Pack 2 (SP2). For more information, refer to this Microsoft web page: Support is ending for some versions of Windows.
On a computer that is running Windows Server 2008 or Windows Vista Service pack 1 (SP1), assume that you use a Windows Management Instrumentation (WMI) call to set the AutomaticManagedPagefile property of the Win32_ComputerSystem class to False. For example, to do this, you run the following command:
wmic computersystem set AutomaticManagedPagefile=False
In this scenario, the system unexpectedly creates page files on all local drives. If you use the System item in Control Panel to change the pagefile size, this issue does not occur. Instead, a pagefile is created only on the system drive. For more information about this method, see the "More information" section.
