How to Increase Cache Size

by Charles Poole

The Windows 7 operating system uses a cache to decrease the time it takes to locate commonly used files on the computer's hard drive. If you would like to increase the cache size, you will need to use the Command Prompt or the system's registry. You don't have to be a computer programmer to perform this task. You can do it yourself with little hassle and minimal knowledge of the subject.

Command Prompt

Click the "Start" button and then click the "All Programs" button.

Right-click on the "Command Prompt" option. Select the "Run As Administrator" option from the menu.

Type "fsutil behavior set memoryusage 2" into the command prompt and press the "Enter" button.


Click the "Start" button and then click on the "Search" bar.

Type "regedit" into the search bar and press "Enter."

Navigate to this path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSe\Control\FileSystem.

Click on the "NTFS Memory Usage" option on the right. Set the "Data" number to "2" and click the "OK" button.

Click the "Start" button and then click the "Restart" button. Once the system restarts, the changes will take effect.
