Fix service host superfetch High CPU Usage

it’s trying to be clever, superfetch is kind of like drive caching, the service will basically try and copy all your most commonly used files into RAM for faster access the next time you need it. It’s all well and good if you have a modern machine with SSD’s and shit, but windows 10 doesn’t really care about stomping older hardware.

The reason it puts your HDD to 100% is because of the amount of IOPS, windows isn’t necessarily maxing out the actual transfer speeds of the drive, but it is maxing out its ability to respond to input/output requests. Windows search indexing does the same thing.

1. Disable Superfetch service to Fix Superfetch High CPU Usage

Local Service (Network Restricted) contains a lot of, how would I say, sub-services, and one of these sub-services is causing Service Host: Local Service (Network Restricted) to use CPU to its maximum.

So to improve your performance, and get rid of the high CPU usage, you have to disable Superfetch service, and here’s how to do that:

  1. Go to Search, type services and open Services. or Hold the Windows Key, while pressing “R” to bring up the Run dialog box.
  2. Type “services.msc“, then press “Enter“.
  3. The Services window displays. Find “Superfetch” in the list.
  4. Right-click “Superfetch“, then select “Properties“.
  5. Select the “Stop” button if you wish to stop the service.

after disabling Superfetch service, your CPU usage should get back to normal and you’ll be able to continue with work on your computer without any problems.


2. Run SFC and DISM scan

If Service Host is causing high CPU usage, that can sometimes be due to file corruption. Your system files can get corrupted, and if that happens, you can repair them by running an SFC scan. To do that, follow these steps:

  1. Press Windows Key + X to open Win + X menu. Select Command Prompt(Admin) from the list. If Command Prompt isn’t available, select PowerShell (Admin) instead.

  3. SFC scan will now start. This process can take about 10 minutes, so don’t interrupt it.

After the SFC scan is finished, check if the problem is resolved. If the issue still persists, or if you couldn’t run SFC scan at all, you’ll need to use DISM scan instead. To do that, follow these steps:

  1. Open Command Prompt as administrator.
  2. When Command Prompt starts, enter DISM /Online /Cleanup-Image /RestoreHealth.
  3. DISM scan will now start. This process can take 15-20 minutes so be sure not to interrupt it.

After the DISM scan is finished, check if the problem still persists. If you were unable to run SFC scan before, be sure to try running it now. After both scans are completed, the problem should be completely resolved.
