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 here AMD Athlon X2 L310

    Restarting computer goes to update screen until 30% and reboots again (normal thing for windows updates) and then the windows flags without the animated dots. Must power off. Start again and get widows flags without animated dots. Must power off (2nd time). Start again and thankfully it starts recovery and 15 minutes later it is back to normal. But the update is waiting in windows update for a restart - DON'T DO IT as it will do the same thing again. For now the only thing to stop the crap is to hibernate.

    Microsoft support was  USELESS. They started attempting to do an update via ISO.

    It will be hibernate until they get their act together.

    I just hid the update and its working for me (that is Microsoft doesn't try to re-download the update automatically) also hope Microsoft comes up with a fix cause after reading thru all the replies I realise everyone is settling with either disabling (MU) or show/hide (MU) ....BTW if anyone comes up wit a genuine fix feel free to reply thanks

    Tested now on a Windows 10 Home Fall Creators Update:

    while the KB4056892 was downloading in Windows Update, I managed with the Hide/Show troubleshooter to hide the update, then restarted the pc.

    Now the KB4056892 is not installed and is ignored by Windows Update!

    I was finally successful in hiding/blocking KB4056892 using Hide/Show Troubleshooter.   The key, as you pointed out, seems to have been restarting the PC after hiding it. I have Windows Update Service enabled again and (so far) it hasn’t tried to sneak it back onboard!
