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?

    Why are you posting this over and over?

    I don't believe any of this crap that Microsoft have told you.

    You didn't say that what you did has worked.

    Others have posted that installing a new copy of Windows 10 has not fixed the issue.

    In my case, my AMD computer that was made unbootable when trying to install this update was a brand new install of Windows 10 version 1709. In was not an upgrade from any previous version of Windows.

    Sorry I am new to the forum and tried replying to as many as I could.

    The solution I posted worked and if you are willing to do the same, I expect it will work as it did by the second level technician from Microsoft did to my computer.

    My computer has AMD X chip and is 32-bit because some Apps I have are old, since the 32-bit era (XP and 7).

    What is funny is why the previous too many updates workrd in presence of the same errors MS Lev-2 Technician said exist?

    Definitely in my personal opinion it is something that MS should not have created in this newest update of 2018-1

    It worked and the computer is running perfectly.  But I have to spend a lot of time now trying to install all the apps and relate them to their data.

    I have plenty of data on additional three hard drives.

    Some apps are no longer able to work on the new Windows-10 that MS Rep installed a fresh.
