RAM or computer memory helps your computer load quickly and complete processes in a timely manner. When your computer runs low on memory, it runs much slower. Microsoft created a way to use a small amount of hard drive space to act like memory when the computer memory runs low. This virtual memory can make a noticeable difference, but may be able to have more of an effect if you increase your virtual memory. Increasing the virtual memory in Windows 7 or Windows Vista is pretty easy, and only takes a few minutes.

From the Start menu, open the "Control Panel."

Open "System and Maintenance" in Windows Vista and Windows 7. Click on the "System" icon.

In Windows Vista or 7, click on "Advanced System Settings." If prompted by Windows Vista, select "Continue."

In the menu that appears, select the "Advanced" tab. Locate for the performance option. Under the "Performance" tab, select "Settings."

Switch to the "Advanced" tab in the new pop-up menu. You can now see the amount of virtual memory your computer has. According to, your virtual memory is 1.5 times the amount of hard RAM you have.

To increase your virtual memory, click on "Change" to set the virtual memory to a higher value. If you have a large hard drive, you can alter the virtual memory by 3 to 4 times. If you have a smaller hard drive, you can see a noticeable difference by only doubling your virtual memory.
