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?

    Don't hold your breath on Microsoft fixing this. They only have to support Windows 10 on systems that the manufacturer's support it on, and no manufacturer is going to have 10 support for an ancient 939/AM2 machine.

    This is wrong assumption. Nobody said that it is not compatible. In fact the upgrade assistant showed that its compatible. If I knew it's not compatible and that the OS would kill my machines few months later, I wouldn't' buy the licenses. It's simple.

    I am helping hundreds of people with this is issue. The fix is actually rather simpler. Here is the steps to fix it:

    Visit https://www.ubuntu.com/desktop and download 16.04, install by removing windows completly.

    There is hundreds of software for replacement, and if the one you need is windows only, you can run windows application on ubuntu with wineHQ or a paid option.

    Enjoy!

    So EJ, you work for Ubantu or what?

    Yes, that is exactly what we need a OS that may or may not address the Meltdown and Spectre issue. I really don't want to reload Windows 10 much less a different OS in place of it. Thank you so much for going off the rail with this "helpful" reply.

    AM2 CPUs are fully compatible with Windows 10, and this bug is not only in Windows 10, the bug is also present in Windows 7 with update KB4056894, and in Windows 8.1 with KB4056898, so they have to fix it anyway, because is affecting all the current supported Windows versions.
