    windows 10

    Disk usage sporadically (For long periods of time) 100%, culprit:

    Almost always 'System'.

    How do I fix this? It's infuriating.

    PC specs available on my profile, kindly ask for any other info - I'll provide as quickly as I can.

    Thank you in advance

    Hi stwn,

    Lets start with verifying the system files

    Disk usage sporadically (For long periods of time) 100%, culprit: Diagnostics Test Disk usage sporadically (For long periods of time) 100%, culprit:
     System File Check

    Please try following:
    • Open an admin command prompt
    • Copy/paste "sfc/scannow" (without quotes) and press enter
    • When it finished reboot your system
    • Open again an admin command prompt
    • Enter sfc/scannow again

    If sfc/scannow says "Windows Resource Protection found corrupt files but was unable to fix some of them" after the second SFC, please upload the cbs.log file located at %systemroot%\Logs\CBS\, if the file is too large try a 3rd party uploader like dropbox, onedrive, google drive, mediafire etc.
    System File Check(SFC a.k.a. Windows Resource Protection) needs to have your system rebooted in order for sfc to try to fix the problems that it finds.

    Make a photo of SFC and post it.

    Please fill in your system specs
    Please follow this tutorial and download the tool. The tool will give you detailed information about your system specs, please fill in your system specs more completely.
