Disable Superfetch permanently

Anonymous

We use Windows 10 version 1703 with underlying datastore as SSD for our performance activity.

High CPU utilization was seen after the completion of workload, as confirmed from task manager cpu hike was caused by Superfetch.

The Superfetch service was disabled and stopped from services.msc and same updated in regedit on Golden image. When the base image was used to clone new windows machine, Superfetch was enabled and running on these new cloned machines. 

We do sysprep for cloning of new machines and looks like sysprep enables the service.

Is there any permanent way which can be used to disable Superfetch on Golden Desktop. 

Please assist.

Thanks in Advance,

Anuradha

    Hi Arthur,

    Please find my response inline below -

    • Is Superfetch available on the list of services for your Windows 10 device? - **Yes, we had disabled the superfetch service on golden image. Also edited the EnableSuperFetcher to 0 (***HKLM \ SYSTEM \ CurrentControlSet \ Control \ Session Manager \ Memory Management *)
    • Is high CPU usage for Superfetch showing even before?- We run performance workload and CPU spiked to 100% after completion of workload. Looking at task manager we noticed "Service Host: Local System (Network Restricted) (8)" was consuming highest CPU.
    • If no, when did the issue start to occur?

    All windows vms are hosted on shared SSD datastore. After taking reference from multiple online sites, for better performance optimization we want to disable Superfetch for all windows machine.

    http://www.thewindowsclub.com/disable-superfetch-prefetch-ssd

    Expected Behavior:

    Our tests runs on scale of 70-80 vms, hence we want to disable superfetch on Golden desktop and after cloning the same setting should be applied on all newly created vms.

    Actual Behavior:

    After cloning new vms with sysprep , the superfetch property gets reset on newly created vms. The superfetch is enabled and regedit value is reset to 3.

    We are using WIndows 10 version 1703.

    Please let us know how best we can achieve it.

    Thanks,

    Anuradha

    Hi,

    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?

    Regards.
