    You need to use the offwindir and offbootdir options, something like:

    sfc /SCANFILE=d:\windows\system32\kernel32.dll /OFFBOOTDIR=d:\ /OFFWINDIR=d:\windows

    The drive letter will depend on where you OS drive is as it may not be C:, could be D: or E: or ...

    You can find it by entering bcdedit. Look at the

    osdevice partition=


    line.

    That would be

    CD system32
    sfc /scannow

    But that won't work as you are not in the Windows directory of the OS boot drive.

    Do as I showed in my previous post and it will work.

    Dism /Online /Cleanup-Image /StartComponentCleanup
    Dism /Online /Cleanup-Image /RestoreHealth
    SFC /scannow
