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?

    If sometimes the link don't get you in the correct place it's only a matter of cleaning cookies for answers.microsoft.com.

    Well, it's nearly 14 days and my machines are still downloading and installing the faulty update. This is really retarded. It's obvious that the MS statements about blocking the update for affected CPUs wasn't true.

    I had same problem. Once the update has been downloaded, it seems nothing will stop W10 from attempting the update. There may be a way, but I never got any of the suggestions to work. In end, I downloaded a clean Win 10 iso from MS and did a clean install. THis got us back working withing 8 hrs after 3 weeks of broken Windows 10. Really hard to believe that MS could screw up so badly.

    I fixed mine by disabling Windows Update. Services.msc, stop the windows update services, set it to disabled and set the auto recovery to none. After that, it rebooted and didn't download the failed update again.
