    Cannot upgrade from Win 7 to Win 10 - "unknown error"


    I am trying to upgrade from Win 7 to Win 10. Before proceeding I installed all the required Win 7 updates, then attempted to install Win 10. However every time I try I get:
    "Code 80070780 Windows Update encountered an unknown error."
    See attached screen captures.
    "Get help with this error" is not helpful. I've clicked "Try again" 4 times now, always the same problem.
    Any ideas?

    80070780 is a rather generalised File system Error - this would suggest to me that the actual install media downloaded for the upgrade has been corrupted

    It's possible to download a new copy from Microsoft and use this to either Upgrade or Clean install

    The Upgrade details are here ...
