When you open Task Manager a little bit, you’ll see that svchost.exe service host: local system (network restricted) is causing the problem of high CPU usage. To improve your Windows performance, and get rid of the high CPU usage, you have to disable Superfetch service. Superfetch used to pre-load data from hard disk into RAM memory. So let’s follow this steps.
- Click search on Cortana, type “services” then tap on Services.
- Scroll down to Find Superfetch service, right click on it and click Properties.
- Choose Disabled then OK.
- Restart your computer.
After disabled 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.
