    WMI Provider host taking up 60% CPU, computer almost unusable


    WMI Provider Host is taking up around 60% of my CPU since the last 1903 update.
    Additionally the service host windows management instrumentation is taking up 10%

    All my drivers are updated.


    This makes my laptop almost unusable. So i really want some help here.

    I got following somewhere, which solved this issue on a friend's machine.

    Event Viewer > View menu > Show Analytic and Debug Logs

    Open the main Applications and Service Logs and drill down to:
    Microsoft > Windows > WMI-Activity > Operational
    WMI Provider host taking up 60% CPU, computer almost unusable-wmiactivityerror.jpg

    Look for red-marked "Error" entries. Click on one, and note the ClientProcessID number—see screenshot above, where number = 19204.

    Now open Task Manager > Details tab and look for the number, eg 19204.
    If you don't see it, check the Services tab.
    Whatever program/app is associated with the number may be your problem. I say "may" because some errors may not be serious. Probably best to make a list of apps associated with Errors, and then disable or uninstall the service or app one-by-one until you find the culprit.

    You could also post the list here, and someone may recognize a frequently troublesome app.

    The problem was the Razer Game Scanner service.

    Thank you!
