    SVCHOST using 100% DIsk

    Saltgrass,

    If I start Sysmain, the disk usage goes up to 100%. I then stop Sysmain and disk usage goes down.

    Thanks,

    Tony

    How do I stop my disk usage being at 100% on Windows 10?

    How do I stop my disk usage being at 100% on Windows 10? Below is what I've tried

    • Changing Link Storage Technology in Intel Rapid Storage to be off
    • Restarting or Disabling Windows Search service
    • Restarting or Disabling Windows Superfetch or SysMain service
    • DISM and SFC scans
    • Checking for hard drive errors in CrystalDiskInfo
    • Running programs as administrator
    • Changing the security of backup programs and high disk usage programs to give my user all the permissions in the Properties
    • Looking at Task Manager to find the cause (the processes listed don't add up to 99% or 100%)

    I'm using Windows 10 20H2
    Is there any other suggestions I can do?

    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:
