  1. Nearly always at 100% disk


    My PC is nearly always at 100% disk usage, it's either "system" or "Antimalware service executable" or "Sysmain". It's always something, I always do the updates, restarts when it asks, etc. Yet, every day is another one, surely windows 10 isn't updating every day, so what is my PC doing? Nearly always at 100% disk :(

    I want it to stop doing unwanted updates or antivirus scans every single day, I can't do anything as it takes 100% disk. Help me, please!

    Clean install, disk usage at 100%

    I've seen that article. and I am in fact not running that driver. I followed the steps and it does not appear in the list.

    Disk is always at 100%

    Hi Richard,

    Some bugs or disk drive errors may cause high disk utilization. If your task manager shows 100% disk utilization, you may need to optimize Windows by following these troubleshooting methods:

    Disable Windows Search

    Some bug in Windows 8, 8.1 and 10 causes some "search loop" that causes maximum utilization of your disk. To disable
    Windows Search, kindly follow these steps:

    • Press Windows + R to open Run.
    • Type services.msc and press Enter.
    • Scroll down to find Windows Search, right-click it, and select
      Properties.
    • Change the Startup type to Disabled and save the changes.

    Disable Superfetch Service

    Superfetch service has been identified as a possible cause of 100% disk utilization on Windows 10. To disable Superfetch service, kindly follow these steps:

    • Press Windows + X and select Command Prompt (Admin).
    • Type net.exe stop superfetch and press Enter.
    • Wait for a minute for the changes to apply and close the Command Prompt.

    Let us know how things goes.

    Regards.

    Nearly always at 100% disk

    Nearly Maxed CPU, Memory, and Disk

    My computer is pretty old now. I think it is around 6-8 years. Yeah. No taking this ole beast back anywhere.

    Just to clarify again I had this problem while on Windows 7, I thought after wiping the system and such and having no fix, I would take the step up and upgrade to 10 and see if that did anything. But no, same as before.

    I have added some parts of my system like you have. I don't know what brand my memory I have is. If you need this I can try find it at some point.

    I have 192GB free on C.

    While running HD Tune my disk went to 100% but in the image below this time there is at least a reason for it. Whereas in my third image on my first post there doesn't appear to be anything?
