Change the size of the virtual memory paging file.....

You must be logged on as a Administrator or a member of Administration group to do this. If your computer is connected to a network, network policy settings may also prevent you of completing this procedure.

• Click and open Control Panel.
• Click Performance and Maintenance and then click System.
• On the Advanced tab, under Virtual Memory, click Change.
• Under drive (volume), click the drive that contains the paging file you want to change.
• Under Paging file size for selected drive, click Custom size.
• Type a new paging file size in megabytes in the Initial size (MB) or Maximum size (MB) box, and then click Set.

If you decrease the size of either initial or maximum page file settings, you must restart your computer to see the effects on those changes. Increases typically do not require a restart.

To have windows choose the best paging file size, click System managed size.

For best performance, do not set the initial size to less than the minimum recommended size under Total paging file size for all drives. The recommended size is equivalent to 1.5 times the amount of RAM on your system.
