    task manager - local system service host with high CPU usage

    Can anyone explain what is happening here?
    From the moment I switch ON my desktop until switching OFF (working for 12 hours) the local system service host is always between 30% to 40% regarding CPU usage.
    Why? How to stop it?
    This does not happen in my Microsoft Surface Pro machine. Both machines, desktop and Surface have the same software installed so it's hard to believe this CPU usage is software based.

    have a look at resource monitor to see if you can see what process is causing it... Figuring out why my SVCHOST.EXE is at 100% CPU without complicated tools in Windows 7 - Scott Hanselman

    So let me see if I'm reading this correctly, it's Windows update that is creating the problem here, correct?

    Yes. I would leave it to finish and then reboot.

    EDIT - you can reset it if it never seems to finish but there were lots of updates yesterday, I'd leave it for a few hours or overnight...
