How to Enable or Disable SuperFetch in Windows


SuperFetch (aka: Memory Prefetcher) is a service that was introduced with Vista.

SuperFetch is an enhancement of the 
Prefetcher from previous versions of Windows. The Prefetcher is in charge of storing program information so that often-used programs and processes can run faster.

SuperFetch keeps track of which applications you use most and loads this information from the hard drive into RAM so that programs load faster than they would if the hard disk had to be accessed every time. Windows SuperFetch prioritizes the programs you’re currently using over background tasks and adapts to the way you work by tracking the programs you use most often and pre-loading these into memory. With SuperFetch, background tasks still run when the computer is idle. However, when the background task is finished, SuperFetch repopulates system memory with the data you were working with before the background task ran. Now, when you return to your desk, your programs will continue to run as efficiently as they did before you left. It is even smart enough to know what day it is in the event you use different applications more often on certain days. Basically, SuperFetch attempts to predict which applications you will launch next and preloads all of the necessary data into memory.

Sometimes SuperFetch may cause high disk usage.

If you run Windows from a 
SSD or M.2 instead of a slow spinner hard drive, then you may not see any performance gain from SuperFetch to justify the drive usage from it.

If you like, you could disable SuperFetch to see if you have any performance gains with it enabled or disabled.

This tutorial will show you how to enable or disable SuperFetch in Windows 7Windows 8, and Windows 10.

 

You must be signed in as an administrator to enable or disable SuperFetch.

This will affect:

- Prefetch
