    KRZ,

    I am not quite sure from your responses whether or not SFC now succeeds on your computer.

    My SFC kept failing despite using the suggestions that others had made but has just succeeeded on all three of my computers by using Bastet's variant method -

    1 Restart the computer
    2 SFC /ScanNow
    [no further reboots/restarts - just continue in the same session]
    3 dism.exe /Online /Cleanup-image /Restorehealth
    [no further reboots/restarts - just continue in the same session]
    4 SFC /ScanNow [This fixes the failures & further, unnecessary, SFC runs just report no problems]

    Yeah, my enquiry was more general: why (if) should I run it in the first place?

    SFC and/or DISM in fix mode generates a lot of unnecessary junk under C:\Windows\WinSxS\Temp (which ultimately gets deleted with the maintenance run or similar) - hence my reluctance to run them in the first place. That's all.

    This is consistent with my early successes having restarts before and after CU KB4507453 18362.239

    Machine 1:

    - no restart

    sfc /scannow
    dism /Online /Cleanup-image /Restorehealth
    sfc /scannow

    - restart ( after CU .239 )


    Machine 2:

    sfc /scannow
    - restart ( after CU .239 )

    sfc /scannow
    dism /Online /Cleanup-image /Restorehealth
    sfc /scannow
