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?

    Today I got another KB4056892 update and it is pending a instal.  The known issues states they are not sending them for systems with AMD CPU's.

    How to exclude the Update:

    • If possible in your Windows 10 version, set your connection as "metererd", this will stop automatic download of updates
    • use the Hide/Show troubleshooter to hide the Update
    • if the Update is not "waiting for restart" in Windows Update, you can restart the pc now
    • if instead the Update is in the "waiting for restart" state, it is already listed in the uninstallable updates so you can uninstall it How to Uninstall a Windows Update in Windows 10 and then restart your pc
    • wait some minutes and then check Windows Update to verify that the Update is now ignored
    • reset your connection to not metered

    Tested on Windows 10 Fall Creators Update Home and Pro.

    "To prevent AMD customers from getting into an unbootable state, Microsoft will temporarily pause sending the following Windows operating system updates to devices with impacted AMD processors at this time:

    January 3, 2018—KB4056892 (OS Build 16299.192)

    Unfortunately, I believed this and resumed updates - KB4056892 installed on my HP Pavilion laptop with a Turion 64 X2 and I had to do another restore.  If Microsoft paused this update, they didn't implement it correctly

    My intel cpu machine wont boot after the update.

    But I get an animated logo for a bit then no boot device available.

    Cant use USB to "upgrade" the installed version of windows because you must beable to boot into that version of windows for the upgrade to run 

    Safe mode does not work.

    Can get to command prompt, and other repair options.

    when restoring to restore point created by critical update (which I think fails because restore point does not go away) still cant boot  {{ dont have patience to watch the system restore process}}

    Any clues as to what to try with out a fresh new install ??

    Have the same AMD problem. Talked to a supportperson at Microsoft earlier today. He said there will be a AMD fix for kb4056892, today or latest tomorrow. Lets see if that happens... Hope so.
