How to disable Superfetch or Sysmain?
If you are using a system that is limited in terms of RAM and CPU, then disabling the Superfetch process might be a good idea. You should consider disabling this process only if you are facing any of the issues mentioned above. Otherwise, keeping it turned on will make the app loading speed on your Windows system faster.
- Press Windows Key + R, and the Run dialog box will show up.
- Enter “services.msc” in the Run dialog box and press the Enter key.
- When the services window shows up, look for the process named “Sysmain.” If you are an older version of Windows 10, then you might see the process as “Superfetch.”
- Right-click on it and choose “Stop.”
- Now right-click on it again and choose “Properties.”
- Under the “general” tab, click on the drop-down menu next to “Startup type” and choose “Disabled.”
- Click on Apply, and then click on Ok.
You can even use the command prompt to perform the operation.
- Click on the search bar and search for “command prompt.”
- When it shows up in the results, choose “Run as an administrator.”
- In the command prompt window, enter the following command and then press the Enter key.
sc stop “SysMain” & sc config “SysMain” start=disabled
Superfetch only works as a system optimization feature. So disabling it will have no issues in your system running well. But once you have disabled the process permanently, you will notice that your applications take a lot of time(more than usual) to load up. If you are still experiencing the same system lag issues you were experiencing before disabling the Superfetch(Sysmain) process, this process is not the reason behind the problem. In that case, you should enable it again and let it keep running in the background, making your frequent apps loading time much faster. To enable it again, open up the services window as mentioned in the first method and undo every change you have made to disable the system process entirely.
If you want to use the command prompt again to enable it, then, in the command prompt window, enter the following command and then press the Enter key.
sc config “SysMain” start=auto & sc start “SysMain”
100% disk utilization is the most common reason why someone might want to disable the Superfetch or Sysmain process. It is reported that many users were able to get rid of this disk issue by simply turning off the Sysmain process in their systems. If you encounter 100% disk utilization even after disabling the system process, you need to think about upgrading your hard drive. If you are using a traditional hard drive, then upgrade to an SSD. Nowadays, SSDs are much cheaper, and having the windows system installed on an SSD makes the OS much faster and optimized. You will also see improvements in terms of data transfer rates which is one of the main causes of why people opt for SSDs in the first place.
