Windows 10, 8 & 7: Enable or Disable Superfetch

Enable or disable the Windows 10, 8, or 7 Superfetch (otherwise known as Prefetch) feature. Superfetch caches data so that it can be immediately available to your application. Sometimes this can affect the performance of certain applications. It tends to not work well with gaming, but can improve performance with business apps.

To modify whether Superfetch is enabled or disabled, you can perform the following steps.

Disable from Services

  1. Hold the Windows Key, while pressing “R” to bring up the Run dialog box.
  2. Type “services.msc“, then press “Enter“.
  3. The Services window displays. Find “Superfetch” in the list.
  4. Right-click “Superfetch“, then select “Properties“.
  5. Select the “Stop” button if you wish to stop the service. In the “Startup type” dropdown menu, choose “Disabled“.
