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 my AMD Athlon 64 X2 5000+.   Running again after System Restore, then blocked the update using the "Show or Hide Updates" tool.   Thanks for the tips.

    I have the same issue.

    Older AMD processor Athlon 64 X2 6000+ and Win10 Home 32-bit.

    Running fall creators update (Winver 1709).

    After KB4056892 update installs and system reboots, Windows logo appears but no spinning progress circle and system never starts. Repair fails. Only recourse is to reinstall a backed up image.  This happened 3 times in a row.  Arg. After doing another restore, in order to prevent it from installing again (!) I stopped and disabled the Windows update service and downloaded the MS Update Hide/show tool and plan to prevent this update from installing.

    ... windows update keeps insisting on installing this update, if i want to get other updates and there seems no way to block this update. 

    Did you already tried this Microsoft tool "Show or hide updates" troubleshooter ?

    How to temporarily prevent a driver update from reinstalling in Windows 10

    "[the tool / troubleshooter] provides a user interface to hide and show Windows updates and drivers for Windows 10."

    I have a ASRock 960GC-GS FX motherboard and i quickly checked the bios settings and everything is enabled. Virtualization Enabled, ACPI HPET TABLES enabled as well.

    In Windows, Task Manager shows Virtualization enabled.

    Try manually rolling back to some previous restore point. If there is none, you will probably have to reinstall.
