After installation of KB4056892 boot failure, after roll-back error 0x800f0845

Hi,

I have older AMD Athlon 64 X2 6000+, Asus MB, after installation of KB4056892 the system doesn't boot, it only shows the Windows logo without animation and nothing more. After several failed boots it do roll-back then it shows error 0x800f0845. Unfortunately, it seems it's not easy to disable the automatic updates without gpedit tweaks, so it tries installing and rolling-back the update over and over. The sfc /scannow shows no problem, in-place upgrade also doesn't seem to help. I can try full reinstall, but I doubt it will change anything. It seems like the update is binary incompatible with my old CPU. I understand that making the machine unbootable is the best protection from remote exploitation, but I would rather have the OS working. Especially if my CPU is not vulnerable to the Meltdown attack and the MS mitigation attempts for Spectre is more than questionable. I could find only some German and Italian people reporting the same issue (well the CPU is quite pre-historic and the KB update is very fresh), but no info / acknowledgment from the MS so far. I have Czech localization. Could anybody provide more information?

    Same issue on 1709, AMD Athlon 4850e.

    Won't boot until rolling back pending actions using command prompt (recovery option): dism.exe /image:C:\ /cleanup-image /

    hopefully this helps find a solution.   https://aka.ms/D1xb5w

    Feedback Hub is still not working, even with this link. ERROR!

    lionum, that link was for Michelle Her at Microsoft on the issue under discussion on KB update semi-bricking AMD PCs. Not about your not being able to leave Feedback on Hub. Just a FYI.

    Ah, ok.

    Anyway, I think (hopefully) because of many feedbacks the Hub is not working now :)

    You can try temporarily disabling automatic updates. I haven't tried this with regards to AMD cpus. But I had to set manual updates for one of my tablets because of space constraints.

    Anyway, for setting up ONLY manual updates, follow the steps at ghacks:

    https://www.ghacks.net/2017/12/03/allow-only-manual-updates-on-windows-10/

    Setting these steps seems to not affect Windows Defender updates as they are installed automatically.

    The link redirects to the Insiders feedback hub so you would need to be using an Insider account to see it.

    Ok, wow there is some neat stuff  in that feed back hub.  Wish I had become familiar with it before all this happened.  The app does seem a bit clumsy with a mouse and keyboard.  Then and again that could be me.  Heck the KBD even went typomatic  from time to time (never saw that before either).  Oh well I am using a KB4056892 enhanced AMD system.

    And yes it did copy into Word.
