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?

    That's a real shame that the patch didn't create a Restore Point !

    That's bad, really bad, Microsoft folks.

    So blocking the update with "wushowhide.diagcab" is the best solution so far, while we expect a fix by MS/AMD.

    No, it is not needed anymore!

    I have read that, unfortunately, for those who are not in "this state" update was still occurring this morning. It was obviously my case (build 16299.125)

    So I recall what I have done to "block it manually" ;)

    You should be able to hide/block it with a right click on the specific update while seeing the list (see picture as an example) + reboot

    control panel>> system and security >>windows update>> select updates to install
