If you’re running on a speedy modern hard-drive you might see an overall improvement on your system by disabling services like SuperFetch.
Windows has many useful built-in services and applications, but some of them are designed for older hardware. SuperFetch could be one of those system services, and disabling it in Windows 7, and Windows 8 might help the overall performance of your system.
What is Windows SuperFetch?
SuperFetch is a built-in Windows service originally designed to improve loading times for Windows and all installed applications. It does so by analyzing which programs are frequently running and automatically “pre-loading” them in advance by reallocating system resources (mostly just extra RAM) in the background. Note that this often involves writing data to the drive that Windows is installed on. But SuperFetch was made with slow HDD’s (hard disk drives) in mind. With modern 7200+ RPM drives, SuperFetch load time improvement becomes negligible. This is even more true with SSDs (solid-state drives), where the service actually becomes detrimental to both the system performance and the drive’s health.
In Windows 7, click the Start button and type: services.msc in the Search field to open up the Services snap-in.
Or in Windows 8, use the keyboard shortcut Windows Key + R to bring up the Run line and type: services.msc and hit Enter.
Scroll down the services page and right-click on the one named Superfetch. Select Properties from the context menu.
On the General tab, click the menu labeled “Startup type.” Choose the Disabled option, and if possible, click the Stop button below it. Press OK to exit and save changes.
SuperFetch should now be disabled and won’t run again unless you manually go back in and set it to Automatic startup. If you test this out and experience an increase in system speed, definitely leave us a comment and let us know. Or, if it doesn’t help, we’d like to hear that too!
