Windows 10: Disabled SuperFetch but system is so slow now

Good day, I received a system that ran very slow in Windows 7 because of svchost. exe eating all my available memory. Upon disabling superfetch, the memory hog cleared however the system is just so slow now and doing basic tasks takes forever. I ran a bad sector test on the 500gb 7200rpm hard drive and it came back totally perfect, no issues. Is there any way i can re enable superfetch but not develop the same memory hog situation again? Thanks in advance.

Disable Superfetch permanently

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.

 

Superfetch disable

In Windows 10, v1809 Superfetch is no longer listed as a service.

How can it be disabled - perhaps via the registry?

Thanks.

 

Disable Superfetch permanently

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.

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
