    2) Establish a Clean Boot to see if that resolves it:

    3) Run System File Checker/DISM in WIndows 11:

    4) If that doesn't fix it then you can do a Windows 11 Repair Upgrade which reinstalls Windows while saving your files and apps in place, brings it up to the latest version by the most stable method, takes about an hour and resolves most problems: https://www.elevenforum.com/t/repair-install-wi...

    Feel free to ask back any questions. Based on the results you post back I may have other suggestions if necessary.

    Happy Holidays!

    Windows 10 & 11 idle high ssd usage and high cpu usage

    Hi Dushan. I'm Greg, 10 years awarded Windows MVP, specializing in Installation, Performance, Troubleshooting and Activation, here to help you.

    1) Run the SSD maker's diagnostic toolkit from the Support Downloads web page for the drive model; if none then use one of these:

    https://mashtips.com/ssd-health-test-and-perfor.... If it fails contact the SSD's Support under warrranty if it's within a year of purchase.

    Follow this with a full Disk Check: https://www.groovypost.com/howto/check-hard-dri...

    When I open File Explorer, High CPU usage in Win 11.

    Windows Explorer high CPU usage as Apps or Background Process...

    3May2018...

    Running Windows10 Home Ver 1709 latest OS Build on

    Intel Core i5 CPU @ 3.8GHz.

    Recently Windows Explorer has been running at high CPU usage 45% to 50%

    Even when I am not using File Explorer - Windows Explorer runs as a Background Process as same high CPU usage...

    First when will Microsoft stick to the new name File Explorer - instead of showing Windows Explorer as the app in the Task Manager...confusing :-(

    Two - I saw someone else with the same problem and a ridiculous multi step cumbersome solution of creating another account (where Windows Explorer did not have high CPU) and then a painful exercise of trying to migrate all applications and files from one
    account to the other.

    Apparently the original user account may have had a corruption....

    Are there any simpler explanations out there on how to fix run away Windows(File) Explorer???
