Can’t locate the Superfetch Service on Windows 10? Look for SysMain instead!

In the latest builds of Windows 10, the Superfetch service is not displayed. How to find it?

Today’s worldwide web abounds valid instructions emphasizing the significance of disabling the Superfetch Service when the Windows operating system is installed on an SSD.

We have recently received a support ticket from one of our regular customers. He mentioned that they wanted to disable the Superfetch Service but could not locate it in the list of available services.

So, why is it no longer visible on Windows 10?

The answer to this question is simple. Microsoft decided to rename the Superfetch service to SysMain in its latest Windows builds. This service can be disabled whenever you are certain that it is causing high CPU usage on your device.

Therefore, locate SysMain, perform a double-click on it, choose “Disable” and finally click “OK”.

Superfetch can sometimes consume a lot of CPU resources and RAM. It may drive your disk usage up to 100%, raise CPU temperatures, and decrease your computer’s speed. If these problems persist even with Superfetch turned off, go ahead and turn it back on — your performance issues aren’t being caused by Superfetch.

    Thank you so much for this! I struggled for days trying to figure out why my disk usage was at 100 and this is the only place I found the fix. I found a ton of articles referring to stopping superfetch but none of them worked because of the name change to sysmain. Your article is the only one I found stating this name change. As soon as I stopped sysmain it dropped completely to 0! Thank you, thank you, thank you!!!
