    Question about Superfetch Service

    Hi. My Desktop is an HP Windows 10 Home with Intel i5 7th gen processor and 12GB Ram. A while back I found that Superfetch caused 100% Disk usage which slowed down the computer to a crawl. After doing some research on this issue I decided to Disable the service. Today I did some more research on Superfetch/Prefetch and found this:
    So I went to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\
    Session Manager\Memory Management\PrefetchParameters and changed the EnablePrefetcher value to 2. Then I deleted the contents of the Prefetch Folder(except for Ready Boot) and restarted the computer. Then I opened a few programs and checked the Prefetch Folder and noticed the programs that I opened are being shown in the Prefetch Folder. By changing that registry entry to 2 it is only supposed to prefetch the boot folders. So basically my question is will this only work on Windows Vista or should it also work on Windows 10. Thanks in advance for any replies.

    Hi Mikey,

    We understand that you're trying to disable the Superfetch and other services permanently. You can follow the steps below as your reference:

    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.

    Feel free to post again if you have other concerns.

  3. Disable Superfetch permanently


    Certain programs can be disabled as long as it is on the services list. To isolate the issue, please provide the following information:

    • Is Superfetch available on the list of services for your Windows 10 device?
    • Is high CPU usage for Superfetch showing even before?
    • If no, when did the issue start to occur?

  4. Question about Superfetch Service

    Superfetch does not exist on my computer

    Background: Recently while playing different PC games I ran into massive fps drops occasionally and sometimes even the game just froze for a few seconds.

    This started happening right after a followed a fps increase guide in which one of the steps where to disable Superfetch.

    I returned to the video to revert the steps since I noticed that these fps drops and freezes started occurring after I followed instructions in said video.

    Question: I searched windows for "Services" and then started looking for Superfetch and noticed that I do not even have Superfetch, it just doesn't exist in my services at all. Is it hidden? Does it not exist? How can I make it visible/regain the superfetch
