    I got issue with svchost.exe (netsvcs) in Windows 10

    Today, when I power up my computer, this process was start to run in Task Manager and used my CPU, around 35% and don't decrease.

    I don't know why I got this high usage issue on my computer, but I'm sure that my computer didn't affected by any viruses because antivirus always run and protect my PC.

    Any solution to help me diagnose and troubleshoot it?

    Most likely it is*some software "phoning home" to check for updates.

    How long have you let it*go?

    Welcome!

    Right-click that svchost and select > Go to Services, list which Services are highlighted please.

    (If it was W7/8.1, I'd say that it could be Windows Update bugging - maybe on a triple-core CPU.)

    It showed a few uncommon services, but I found one that related to Windows Update, it's WUAUSERV.

    To confirm that is the culprit, stop the service. It seems WUAUSERV always consumes CPU, from w7 onward, must be well written, not.

    cheers, Paul

    From Vista on... 100% of one CPU core.

    Yes, stop the wuauserv service and see whether the CPU% drops to a more normal level, it will auto-start at the next boot.

    When I stop it, the problem is also gone.

    One tip in this post suggest me to uninstall Windows update (which I recently upgraded, to build 1067). After doing so, it seems the problem is gone, even I turn on WUAUSERV.

    I love to upgrade to 1067 but it seems I have to wait for newer build, which won't have these kinds of errors.

    Given the problem has been around since Vista, I wouldn't hold your breath.

    cheers, Paul
