    CPU Maxes at 100% off disk build


    Dear Forum board
    build number 10586
    I have built an HP Probook 450 G4 from disk from scratch,on starting to build it up I notice the CPU is maxing at 100% straight fromboot with an Ethernet cable in, I did a bit of research and disabled SuperFetchthat helped for a short while.
    By looking at the service host local system, I found thatthe group that has Windows Update in there is what could be causing the problem,so I disabled windows update service, and the CPU dropped.
    On a re-boot I found that the windows update re-starts, Ithen disabled it via the services and re-booted the laptop and the CPU and diskdo not max out.
    Is there a way that I can keep the windows update servicerunning, but not every time, I insert an Ethernet lead it doesn’t max out theCPU and Disk?

    I think it is reasonable to expect 100% for disk activity for short periods on boot up. For example I get this for about 3 minutes after any startup. Sometimes it will be longer if I there have been some recent updates. Similarly CPU will be high for short periods but usually less so than the disk activity.

    Have you tried leaving it running for a while or overnight and then seeing if it runs better? With a new build I would expect it may take a day or two to settle down as there is a lot of background indexing to be completed and prefetch data to be established so that the system can run more efficiently.

    many thanks, I kind of self solved it myself.
    1st step was disable the windows update service
    2nd install the Essential System Updates for Microsoft Windows 10 (off the HP model laptop section) update and reboot
    3rd load the windows 10 update settings, make sure that the windows update service is disabled
    4th the windows 10 update settings will show check for updates.
    5th set the windows update service to manual and then start the windows update service
    6th click on the check for updates
    this should then start to pull updates down.

    at this moment in time the laptop is 88% downloading and has been for over and hour now
