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?

    I'm having the same issue on my AMD Athlon 4850e dual processor machine. I also did a system restore and then paused win 10 updates. My machine hangs very early in the boot process with the teal blue windows logo frozen on the screen. I created another question for my issue, but it definitely seems related, if not identical.

    Try advanced repair. Check fir a system restore point.  If you are lucky enough to have one or u knew to enable then u can restore. After that it is repair keeping files but lose apps.

    Seems the beat current 'workaround' is to pause updates for 35 days - can find the option in the Windows Update Settings -> Advanced Options.

    This provides a brief release from the hell that is Windows 10 and all of its 'intelligence' and gives the 'experts' a Microsoft time to do a proper job on the patches

    Since u have pro then follow the steps to delay updates. You may need to disconnect the internet to be sure the update does not download until set to dekay.
