    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...

    2) Fixes for high SSD usage in Windows 10 and 11:

    3) Fixes for high CPU usage in WIndows 11:

    https://allthings.how/how-to-fix-windows-11-hig...

    https://www.howtoedge.com/solve-100-or-high-cpu...







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

    https://www.elevenforum.com/t/use-system-file-c...

    5) 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. Please report back results for all steps given so I know what else to suggest if necessary.
