Windows 10: Window 10 Service Host Superfetch

I thought I had disabled superfetch in the past but after the last windows 10 update, it is appearing again as service host superfetch. When I disabled it thought it was just superfetch (w/o service host). When I click on properties, it is just showing svchost.exe. This is scary as it doesn't even show superfetch. Does superfetch run even when it was disabled previously?

service host superfetch is causing problems

Service host superfetch is using using a lot of memory and slowing down my computer since I installed the latest Windows10 upgrade-how can I fix this issue.

 

windows 10 Service Host: Local Network

Hi,

Service Host: Local Network contains a sub-service called
Superfetch that is used to pre-load data from hard disk into RAM memory. To improve your PC's performance, we suggest that you disable Superfetch service. Here's how:

• Press Windows key + X on your keyboard, then choose
  Command Prompt (Admin).
• When prompted with the administrator permission, click Yes to continue.
• Type in the following command: net.exe stop superfetch.
• Hit Enter.
• Wait for a few minutes to see if changes can be seen on your computer’s performance.
  
• If you want, you can also run a disk check by typing the following command:
  chkdsk.exe /f /r.
• Press Enter.
• Type Y to confirm the disk check by the time you restart your computer. Please make sure you have closed all of your applications first.

Let us know if you have successfully completed the steps and the result.

 

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
