    Disk Usage at 100% on startup and randomly


    For a couple months my laptop has been struggling due to disk usage issues. I've attempted to search for solutions to this but nothing works for my laptop possibly because each pc is different and my issue might be more specific. Sometimes the laptop struggles to even load desktop and will be stuck on a black screen or the windows blue window will come up telling me it was having trouble starting. Once i do start it up it struggles at random points when im playing a game or using a program. Obviously the disk is just unusually high as no apps are using much of the disk. I've tried repairing a

  2. 100% disk usage

    The most common cause of 100% disk usage appears to be Superfetch and Prefetch, but there are also other causes. You can try disabling both these features and see if it helps.

    This article provides steps to disable prefecth and superfetch:

  3. 100% disk usage.

    Summer has ended and my girlfriend booted her school laptop for the first time in months, only for it to be so unbearably slow that it took several minutes to log in. She handed it to me and said "fix it"... that was 3 days ago and now I am here to humbly
    ask the community what is going on with this GD laptop.

    It boots and task manager reports 100%CPU usage, it then lags for several seconds and displays 100%disk usage with CPU usage bouncing between 30-60%.

    If you leave it alone with task manager running it will eventually quiet down to a reasonable 0-5% disk usage, but doing ANYTHING causes it to bounce right back to 100%.

    I have tried EVERYTHING.

    • disable superfetch.
    • disable microsoft search.
    • disable updates and suggestive tips.
    • updated to the most current version of microsoft. (it hadn't been updated since 2018 when she bought it.)
    • reconfigured AHCI PCIE.
    • changed energy options.
    • disabled indexing.
    • reset the virtual memory.
    • ran disk defragment and disabled all scheduling.
    • updated all drivers.
    • deleted google chrome.
    • Disabled all services that weren't microsoft services and disabled all startup programs (clean boot).
    Still no change in the disk usage.

    Its an HP Laptop model 15-bw0xx with Windows 10 home edition version 10.0.18362

    after messing with it this long im considering replacing the HDD with an SSD but I fear that it wont fix the issue.
