  3. svchost.exe / service host : local system ( network restricted ) high usage memory and CPU

    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.

    Fix svchost.exe service host: local system (network restricted)
