    High CPU usage of System process when idle

    I have updated Windows 10 to H20,the newest version. I installed windows 1 month ago with new pc. But have new issue.
    When i open task manager cpu usage is 0-1%,ok thats fine. But after 4 minutes of idling cpu usage stuck on 7% forever. It goes down to 0% when i touch mouse.
    I scrolled fast down and check that "System"is taking that 7% usage. How to resolve this? I dont have any programs in background.

    [COLOR=rgba0, 91, 106, 1]The weird thing is that everytime when i touch mouse it goes down to 0%. When i dont touch mouse it will stay on 7%.[/COLOR]

    The System process uses amost a whole thread of CPU after PC is idle for a few minutes, and stops using CPU as far as I do something such as moving mouse or pressing keyboards.

    System Idle Process High cpu usage

    No, System Idle Process is *not* causing high cpu usage. It's not causing anything at all.

    System Idle Process is not really any process at all. It's just a number inserted to make the total CPU usage add up to 100%. From the little information you've provided, I can't tell what your problem is, but it's definitely not System Idle Process .
