Optional Update KB3000850

    My modifications to Windows Start menu caused the error


    After running into the same error 80070002 ("failed") as others have after a long process of waiting for the application of KB3000850 to finish, I eventually discovered THIS POST in an MS Answers forum which provided the key solution.

    I use Start8 (although that's not really relevant) and through it had done my standard Start Menu modifications that I do for Win7, moving the assorted dozens of items to my own invented higher-level folders (i.e. "categories"). This reduces the Start Menu "clutter" and I feel more comfortable.

    Well, following the 80070002 error, according to the diagnostic instructions found above-mentioned post I then examined CBS.LOG (in C:\Windows\Logs\CBS) with Notepad and did a "find" for ", error". And sure enough, just as the poster had said, the fact that I had moved several Win8 folders from their original Start Menu locations into my own invented folders was the problem. Each of these corresponded to an ", error" entry in CBS.LOG.

    In particular, all I had to do to eliminate the 80070002 error and allow the KB3000850 optional update to complete was to put back (i.e. recreate, by moving from my own folder location back to where they were apparently critically expected to be by KB3000850) the following:

    C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Accessibility
    C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Accessories\Tablet PC
    C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Accessories\System Tools

    Furthermore, because of an additional move to a sub-folder that I had done which the above poster had not done (and which was revealed by another ", error" item in CBS.LOG), I also needed to recreate one more folder:

    C:\ProgramData\Microsoft\Windows\Start Menu\Programs\System Tools

    In other words, whatever "missing folders" in the Windows 8 \Start Menu\Programs are identified by ", error" items in CBS.LOG, you need to restore them to their original locations.

    And once I completed this restoration process, well now KB3000850 now finally did complete normally and prompt me for a reboot, and it was done!

    Setting up a brand new HP laptop for a friend. Problems installing this update again (third computer for me to have this problem). Tried:
    1. stopping WU service, renaming SoftwareDistribution, restart WU service, run WU - failed.
    2. download full package from MS, manually installed the 2 smaller updates (included on download page) first then the big one - failed.
    3. did sfc /scannow, reboot, ran downloaded package manually - failed.
    4. did Dism /Online /Cleanup-Image /RestoreHealth, reboot, did sfc /scannow, reboot, ran WU and let it go - worked!

    This update has caused me problems too. After about an hour, it still hadn't completed and was causing my system to run VERY slowly. I started Googling the update, which led me here where I discovered I might have bigger problems.

    I keep seeing KB3000850 described as an optional update received in Nov 2014. I've only got this update today (4th March 2015!) and Windows Update is telling me it's an important (not optional) update. What's going on?

    I have been having issues with this kb3000850 update. I got this update a couple of weeks ago marked as important. I have windows update on auto so this update was automatically downloaded to my computer. I did not have any issues with the update being downloaded but only after. Ever since then on start up I have to restart my computer to be able to login with my account details. Also my computer suddenly slows down a lot after a few minutes of activity on it to the point of the mouse lagging when I try to move it. For some reason now when I move my mouse during a video from any site like youtube it stutters the sound.

    Hi - I am new to this forum and have been reading about KB3000850. It has come up as an important update (I have a refurbished computer and had to investigate by elimination which update was causing the fail), and it downloads and installs fine, but refuses to configure on restart (gets to 8%), reports failure and undoes changes. Is it as important as it says it is, as I am fed up with trying to install it. Everything else works fine and all configure properly. Can anyone help?

    I'm also having problems with this update....running into it as I'm also trying to update to Windows 10, but can't.

    I've done many things:

    1) Windows Update Diagnostic several times which has found errors it can and cannot fix
    2) sfc /scannow - found errors it can't fix
    3) ran dism /restorehealth - doesn't fix all errors
    4) ran diskcheck during startup, no errors found

    I've downloaded the update, it installs, and during restart has to finish, but can't so the updates are undone. This update has only popped up recently. The only ", error" in CBS log is this

    2015-08-05 22:52:23, Error CBS Session: 30461961_674738757 failed to perform store corruption detect and repair operation. [HRESULT = 0x80240021 - WU_E_TIME_OUT]

    I've got lots of logs after running these diagnostics...tried to upload the logs, but couldn't get the upload tool to work somehow.... I'm a pretty good novice, but I've been running around in circles and can't seem to make progress. Any help would be very appreciated.

    I could not upgrade on my laptop via update so went direct to ms and downloaded media tool and it went in perfectly. BUT, on my pc, I used the download update in Update perfectly.
