By default, for a Windows 7 computer, virtual memory is handled automatically. A Windows 7 computer uses the concept of paging, where an assigned amount of RAM is reserved for the paging file. This paging file is used by your Windows computer when it is required instead of the physical memory. Paging file size for all drives is already defined by your Windows 7 computer. However, if you wish you can manually change the paging file size.
To change virtual memory and paging file size for drives in Windows 7, follow the below given steps:
1) Click on Start menu and then click on Control Panel.
2) Then, click on “System and Security”.
3) After that, click on “System”.
4) On the left panel, in the bottom, click on “Performance information and Tools”.
5) On the left panel, click on “Adjust Visual effects”.
6) In the “Performance options” dialog box, go to “Advanced” tab.
7) Under Virtual Memory, click on “Change”.
8) Uncheck option “Automatically manage paging file size for all drives”.
9) Select a drive under “Paging file size for each drive”.
10) Select option “Custom size” and enter “Initial size” and “Maximum size” in MB for that drive.
11) Click on “Set” button.
12) Then, select any other drive and similarly change the paging file size.
13) When you have assigned paging file size for each drive, click on “OK”.
When, you are done, click on “Apply” and then “OK”.
