    different result than expected
    did this twice
    ran the commands to ren folder
    after reboot WU gave me updates as before (the above)

    ie the problematic one and those i had previously hidden ( bing drop, ie9 ie10 and ie11)

    80070490 recurred when tried to install KB2904266

    w7 appears to have rebuilt the folders

    OK - windows is supposed to rebuild the folders :)

    Please check that the KB2904266 isn't actually listed in the Installed updates listing - the error is sometimes an indicator that the update is installed (badly)
    If it is listed, please attempt to uninstall it - what happens?

    Conventional wisdom at this point is that a repair install is required.

    I'm not too keen at being defeated at this stage - but it's up to you...

    Here's the instructions for a repair install -

    See what you think.

    Carrying on trying to fix it could take some time as I peck-and-hunt for errors, with no guarantee of success.

    Like I say - it's got to be your choice.

    I don't like admitting defeat either.

    The Repair Install in Windows 7 is really the easiest yet, and rarely fails badly (although it may not work, it usually backs out gracefully).
    It's certainly worth sleeping on the decision- feel free to come back and ask questions, or carry on as we are at present.

    Thanks


    Similar to others I also struggled to find a resolution.
    I ran the Win 7 in-place upgrade/repair and surprise surprise Windows updates is working again.
    Now I have well over 100 updates to install post Win 7 SP1.
    Thanks for the link at the end for the win 7 upgrade/repair. It worked a treat.
