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?

    Just to confirm success with KB4073290.

    My Athlon X2 5000+ computer with windows 10 Pro failed to boot after installation of KB4056892. I solved by getting into windows repair using a installation disc and asking it to repair start up. This it did by removing update. once booted I removed KB4056892 using control panel/programmes and features and postponed any further updates.

    I downloaded KB4073290 from Microsoft update catalogue and following succesful installation and restart I reactivated windows updates which then installed several more updates

    KB4073290 is new cumulative update and replaces KB4056892, so you can just install KB4073290 directly and without KB4056892.

    That's the way I read it. Also that's what I did and all seems to be fine.

    Where do you see that?

    https://support.microsoft.com/en-us/help/4073290/unbootable-state-for-amd-devices-in-windows-10-version-1709

    This is what I see:

    "An update is available to fix the following issue that occurs after you install January 3, 2018—KB4056892 (OS Build 16299.192):

    AMD devices fall into an unbootable state.

    Update replacement information

    This update does not replace a previously released update."

    I am in a before KB4056892 state, not  "after you install" state.

    EDIT:

    2018-01 Cumulative Update for Windows 10 Version 1709 for x64-based Systems (KB4073290)

    Will watch this thread before I implement. Thanks

    I might be missing something, but I don't read to install KB4056892 and then install KB4073290. I read to install KB4073290 only.
