Optional Update KB3000850

  1. #161


    Give this a go from a clean boot environment KB3000850 - BIG update - Windows 8.1.2? - Page 2 - Windows 8 - MSFN Forum

    It didn't work for me but it's got to be worth a try.

    Some searching brought up the suggestion to open an command prompt as administrator and run "sfc /scannow". I did that, it fixed some errors. I then re-tried to install the update and it worked. Hope this helps someone, it got me past my issues with KB3000850.
    Just to update, I ran Dism /Online /Cleanup-Image /RestoreHealth, and sfc /scannow, both as administrator, both found no problems. Just to be sure I also ran sfc /scannow at boot, that also found no problems.
    Tried to install the update, still failed!
    Attached my CBS log if anyone knows how to look into it.
    Success on my desktop!

    Decided to try again. Ran Dism /Online /Cleanup-Image /RestoreHealth, no problems reported. Ran sfc /scannow and it repaired some start menu items (which I deleted some time ago as not used):
    Accessibility - Windows Speech Recognition
    System Tools - Default Programs, Task Manager and Windows Easy Transfer.

    I ran the update from downloaded stand alone installer. When it finished and restarted (about 20 minutes for the update and restart) I ran Windows Update and it showed the same update reference with an 11mb file still needed to be installed. Downloaded that and restarted, and all seems fine. No noticeable change in PC speed, so it seems to have finally done the job.

    Now to tackle the laptop!

    Same here, after the stand alone install I ran Windows Update again and it brought up an 11mb download. It installed with no problems and everything seems fine. As for speed, it seems like my computer now goes from the welcome screen to the desktop much quicker. Maybe SFC fixed something that was hanging it up there. Or maybe I'm imagining things.

    Did exactly the same thing with the laptop. All went OK.

    The only difference, there was not the extra 11mb update this time!

    All is well.

    Strange that it took quite a few attempts to sort itself out though.

    Solution for two of my systems


    I just registered with this forum to relate to you the solution that worked for me to install KB3000580. Previously, on two Windows 8.1 computers, the update would not install, indicating a failure each time I tried, with no failure code. Here are the summarized system configurations:

    Computer 1-
    Windows 8.1
    OS on HDD
    Page file set to OS partition, automatically managed by Windows
    GUI configured with Classic Shell
    Anti-virus is Windows Defender

    Computer 2
    Windows 8.1
    OS on SSD
    GUI running under Stardock Start8 and WindowBlinds
    Page File set 400min, 2000max on a non-OS partition, non-OS disk (lots of RAM)
    Anti-virus is Windows Defender

    After many update installation attempts on both computers through the Windows Update application and through manual installation attempts of the KB3000850, I only achieved installation failures. Here is what worked for both machines, in order of task performed:

    • turn off all non-critical services via services.msc
    • computer with Stardock Start8 and WindowBlinds - in Services.msc, disable Start8 and WindowBlinds/computer with Classic Shell - set Classic Shell to not start with Windows (bypass Classic Shell start menu)
    • restart computer
    • open a Command Prompt with administrator privileges, run sfc /scannow (it found OS corrupted files on both computers)
    • manually install KB3000850 (use downloaded file from Microsoft)
    • reboot (note, reboot took quite a while as Windows was configuring OS)
    • turn back on services that where turned off during update preparation
    • turn back on/enable full functionality of Start8 and WindowBlinds/Classic Shell
    • run defragmenting software (or Disk Optimizer-TRIM for SSD)


    The update on both computers was completely successful. The update is rather substantial. I recommend you do not skip the last step of optimizing/defragmenting the disk OS partition. After two or three reboots, both computers run just as fast as before the update, and there are no anomalies in any programs or applications. Boot-to-desktop is just as fast as before.

    Wow that's really a lot to go through just to install a simple Window update!!! I guess I just got lucky with my three running 8.1.1 and Classic Shell.

    I am still not positive what prevented installation during the first few attempts, but it apparently was the start menu and GUI customization software- Start8, WindowBlinds/Classic Shell. I don't know if the other items I detailed in the bullets in my post above played a large role or any role in inhibiting installation. Frankly, I had spent so much time trying to get that monster to install, I just pulled out all the stops...and it worked. Both computers are working perfectly now.

    Applied it some days ago on 3 laptops, different makes & 32\64 bit, installed without hiccups and (seemingly) zero problems thereafter.

    FWIW, I am running Classic Shell and had issues. Maybe that is causing problems?

    If so it must be hit or miss. I have Classic Shell and had no problem. Only disabled anti-virus while installing.
