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?

    Make a USB or CD of Windows 10 Boot or Boot-ISO Image from someone else's windows machine.

    I read what you posted, i run into a problem. I don't have windows 10 on DVD or flash drive, as my copy of windows 10 was the free upgrade. And if i did how do you use the raparation tools? step by step would be great.

    Windows 10 ISO is a free download on Microsoft site. I used an Ubuntu Live DVD to move my critical files to a second hard drive. My only visible restore point was after the bad update, so it did no good. Recovery disk was not working nor was my recovery partition. I downloaded the ISO, burned it to DVD on another machine and did an install. This made my old install visible and upon boot, it wanted me to choose which one to boot. At that point I opted to wipe, repartition the drive, and do another totally clean install. I then paused Windows Update and used wushowhide to hide KB4056892. Found out about the new updates and decided to wait a couple days to see how it went for everyone. I'll install this weekend.

    Ok,  I think we got this.

    Here...........

    KB4056892, (AMD fx-8150 64 Bit) results in Windows 10 build 1709 version 16299.192.

    KB4073291, (AMD Athlon X2 6000+ 32 Bit) results in Windows 10 build 1709 version 16299.201.

    And in your case.

    KB4073290 results in Windows 10 build 1709 version 16299.194 (on 64-bit machines)

    Both  KB4073290 and KB4073291 supersede / replace KB4056892.

    All's well that ends well, still and all, makes you want to go out in the back yard and "burn one".

    As far as I am aware, KB4073290 supersedes KB4056892.

    On my machine I uninstalled KB4056892 (using Control Panel) after the failure to boot when it tried to auto install. When KB4073290 was released I downloaded it from the Microsoft Catalog, double clicked it and it installed itself. KB4056892 was not present, so it could not have been patched.

    KB4056892, (when it works!) results in Windows 10 build 1709 version 16299.192.

    KB4073290 results in Windows 10 build 1709 version 16299.194 (on 64-bit machines)

    KB4073290 appears to me to be a Cumulative Update, that is one which can be installed on any version of (64-bit) Windows 10 build 1709, and will bring it fully up to date.

    Dave.

    It is a bit confusing as to what breaks/fixes what.  Posting what happened here after 01/04/2018 can add some information.

    AMD fx-8150 / ASUS M5A95 /  Win-10 64 Bit. 

    • KB4056892 is the only related update installed.
    • ASUS Ai Suite 2 stops working  with errors.

    See......

    https://answers.microsoft.com/en-us/windows/forum/windows_10-update/kb4056892-breaks-asus-ai-suite-ii-on-amd-fx/f1d88d90-42a4-4476-b2ea-fe9cec00bf82?tm=1515361378804&auth=1

    AMD fx-6300/ GIGABYTE GA-78LMT  / Win-10 64 Bit.

    • KB4056892 is the only related update and installed with no apparent damage.

    AMD Athlon X2/ASUS M3A78-V3  Win-10 32 Bit

    • KB4056892 causes unbootable state.  Will not recover from checkpoint.
    • Restored from REDO system image.
    • Blocked KB4056892.
    • KB4073290 is for 64 Bit OS so does not apply.
    • KB4073291 installs correctly.
    • KB4056892 still shows as failed in update history.
    • Show/Hide tool shows no updates blocked.  KB4056892 was blocked and now it's gone.
    • Looking with Show/Hide there is no mention of KB4056892.

    If we could see what updates were installed on an older AMD CPU with Win-10 64 Bit OS it may indicate if  KB4073290 patches or replaces KB4056892.
