    Did you ever find a solution? I'm having the same issue and the above suggestions didn't work.

    Those suggestions didn't help me either, but I fortunately saw the issue go away over the next week without taking more steps. Still hasn't resurfaced, knock on wood.

    I disabled two services in services.msc to get mine to stop the 100% SSD usage: "SysMain" and "Connected User Service & Telemetry". Once these were stopped and disabled, I rebooted the computer and everything worked just fine.

    Hi,

    I had this same issue on my Lenovo ThinkPad - Windows 11 Pro 21H2 - SSD . So I went through:

    Device Manager > IDE ATA/ATAPI controllers **** > Intel(R) 300 Series Chipset Family SATA AHCI Controller

    and had the iaStorAC.sys driver

    I wrote down the device instance path as mentioned in the article and then opened the regedit on the suggested path:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\PCI\<Put your AHCI Controller Value here>\Device Parameters\Interrupt Management\MessageSignaledInterruptProperties

    So I looked up the  MessageSignaledInterruptProperties key, which was set to 1 hex then I put it to 0 hex as described in this article.

    Closed the Registry Editor and Reboot.

    My disk usage came down from 100% to 19% as of now.

    Pretty darn worked for me !

    Big Thank You !
