    Today's (1 Jan 2017) Cumulative Update Won't Install

    The Cumulative Update for Windows 10 Version 1607 for x64-based Systems (KB3213986) that was released today won't install onto my computer. Windows Update would download it and tell me to restart but when I restart, it doesn't seem to even try to install the update instead it stays at the "Getting Windows ready" screen but it doesn't show any install progress then after a couple minutes it just restarts and gives me a message that "We couldn't complete the updates, Undoing changes." I've tried several times with Windows Update and the same thing happens and I've also tried manually installing it from the Microsoft Update Catalog but that also didn't work. The other updates that were available today went through, but not the cumulative update.

    This wasn't the first time I've had problems with cumulative updates but there was always a work-around posted on the forum before but this time it seems I'm the only one with this problem? Can anyone help? I don't even know how to stop my computer from trying to download the update again every several hours.

    For more see the excellent Tutorial section which you are free to browse and search.

    Sometimes certain updates have caused issues- manually download and try that way, assuming there's no fundamental issue with your PC. If it's an MS problem, wait for resolution, and block it temporarily.

    Follow the post on the update in the News section in this forum.

    You might also want to try the Windows Update Minitool (aka WUMT) to see if it will work for you instead. Download from MajorGeeks at Download Windows Update MiniTool - MajorGeeks. Great tool!

    WUMT didn't work so I guess I have to use Winaero Tweaker for now and just not get the update. I did run the Windows Update Troubleshooter as well and it gives me the option to "Repair Windows Update Corruption" by deleting and re-installing updates which I chose to skip and after doing everything else it shows "Potential Windows Update Database error detected" and says it's not fixed. It also shows "Some security setting are missing or have been changed," "Service registration is missing or corrupted," and "Windows Update components must be repaired" and says that these are fixed but they show up over and over again when I run the Troubleshooter again. At this point, is it likely that there's a problem with my PC or something wrong with Windows Update on my end?

    Sounds like you need to fix sthg.
    Try's cautious repair tool and select only the relevant repair.
    If that fails, you may need to do an in-place upgrade repair install (which keeps all programs and most settings).

    Sorry, but are you talking about Windows Repair or one of the System Tweakers?

    Ok, I ran the program and the update still didn't go through. I guess that means I need to do an repair install now?

    Also, Windows Defender stopped working after I ran it, even though I'm sure I only had Windows Update selected. I get the message, "Microsoft Security Client: An error has occured during initialization. If this problem continues, please contact your system administrator. Error code: 0x80070005." Is it possible for me to get Windows Defender working again until I have a chance to do the repair install?

    That sounds like (maybe) a Defender update error. (Defender is updated using the Windows update mechanism).

    If you are concerned, it is possible to update it manually.

    Have you tried this?
    Windows Update - Reset in Windows 10

    You could also try manually downloading the update and installing it.
    Usually a link is posted in the relevant News item in this forum.

    Ok, Windows Defender is working. I guess all that there's left to do is to do the repair install. One last question, would a repair install be enough or is a clean re-install the only solution guaranteed to work?

    Thank you.
