       New #850

    Brink - thanks to your thread here, I've run sfc / scannow a number of times on the Win 7 Pro 64-bit side of my dual-booting Dell (including three times in safe mode), and there are now very few error or warning messages in event viewer. Very nice. BUT ...

    The sfc / scannow end message still says that it could not repair some corrupted files (don't have the exact language). And the CBS.log is not exactly user-friendly.

    Should I attach here that CBS.log? Would you have time to look and advise what it's actually saying?

    If this isn't exactly the right place, is there a forum dedicated to medical advice for CBS.logs?

    Thanks again.

    Hello glnz, :)

    If you like, you can use OPTION THREE in the tutorial to post the sfcdetails.

    Brink - great. Showed very little that remains unrepaired. Here are those lines, which repeat in the various sfc reports.

    I am guessing this makes sense, as I have UNinstalled various MS updates that are designed to prepare my Win 7 to ascend to Heaven and become Win 10. I prefer my terrestrial Win 7. But just a guess.

    What do you think?

    Many thanks.

    These errors are perfectly normal - and MS's fault. There's nothing amiss here
    If you want to get rid of them you'll have to uninstall KB3068708 (and possibly KB3022345) and hide it/them

    Yep, it's just a false hash mismatch from the KB3068708 update. There's nothing that needs to be done or to worry about. :)

    NoelDP - Per your suggestion and a number of other comments, I uninstalled those two updates (in elevated cmd using wusa /uninstall, which can be repeated immediately until you know you got all copies of each update).

    And ... voilą! A new sfc / scannow "did not find any integrity violations". Progress!

    Many thanks to Brink and you!

    Now what to do about diagtrackrunner.exe, which still appears (once only) in my c:/ drive? I have read that it can't be deleted. Please send me links to any good instructions for killing that one.

    There should actually be at least 4 different copies of diagtrackrunner.exe present (if you'd kept your machine up-to-date)

    Why would you want to remove it?

    Just for info... the first two were in KB2952664 and KB2977759 - after that I lose track a little... but I think the later ones are all associated with KB2952664 versions (it's been updated quite a few times since first release in January!)

    NoelDP - It might be a stealth "phone home" app to Microsoft. Please google it - many articles - it's linked to the updates I've been trying to get rid of and for which I needed Brink's thread here to repair my machine.

    But that's "enuff" about this side topic. Let's leave this thread to Brink's great advice about sfc.
