If you don’t see a lot of recent .pf files (see previous post) SuperFetch may have been turned off. Or you may wish to turn it on or off yourself. To do that

  1. Hold the Windows Key, while pressing “R” to bring up the Run dialog box.


2. type “services.msc“, then press “Enter“ or click OK.


  1. When the Services window displays find “Superfetch” in the list.

  1. Click “Superfetch“, then either click Stop or Restart (to the left when using Extended view)

  2. OR right click “Superfetch” and select “Properties“ (either standard or extended view).


Select the “Stop” button if you wish to stop the service. Or “Start” if available and you want to start the service. Remember to click “OK”.
