  • Hi,

    Please run these commands first:

    DISM /Online /Cleanup-Image /CheckHealth

    DISM /Online /Cleanup-Image /ScanHealth

    DISM /Online /Cleanup-Image /RestoreHealth

    When you run the command mentioned above, DISM will try to use Windows Update to replace the damaged files. However, if the problem has also extended to the Windows Update components, then you'll need to specify a source containing the known good files to repair the image.

    DISM /Online /Cleanup-Image /RestoreHealth /Source:repairSource\install.wim

    Best regards,
