Superfetch Disable or Enable?


Superfetch is a Windows service that is intended to speed up application launching and improve system responsiveness. It tries to do so by preloading programs you frequently use into RAM so that they don’t have to be called from the hard drive.

However, Superfetch can run for considerably long time in the background and occupy too many system resources (such as CPU, memory and storage). This will sometimes slow down your computer. Therefore, you may be considering disabling it.

Whether Superfetch should be disabled?

In fact, the answer to this question is it depends. If Superfetch does not take up too many resources, you can just leave it as it is. But if this service is decreasing your computer’s running speed, it is recommended that you turn it off.


You can just disable it and test the result for yourself. There is no harm in doing this.
