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?

    KB4056892 patch has failed to install twice on my desktop Dell Inspiron 531. (AMD Athlon 64 X2 Dual Core Processor 5000+ 2.60 GHz)  It hangs on Windows Logo at reboot. No drive activity, no keyboard or mouse input. I have to do system restore to get the PC running again. 

    I have run Windows Show/Hide tool in attempt to pause installation of this update.   Yet to be seen if it actually worked.   http://download.microsoft.com/download/f/2/2/f22d5fdb-59cd-4275-8c95-1be17bf70b21/wushowhide.diagcab

    Jaroslav,

    Yes this is a nasty problem and apparently a nastier fix.  What is worse, with less severity  the "fix" appears to also affect newer AMD/ASUS combinations.  On this AMD FX 8150 system ASUS utilities stopped working after KB4056892.  I am using a workaround and just starting to look at the errors.

    What is Ironic is that last I read AMD doesn't think they have more severe of the problems.

    I have two other AMD systems here.  The remaining two will not be powered up without blocking  internet access, such that I can get some work done.

    All told, I have five  cans of worms here.  Two of them are open, and I'm not having fun.

    Looking around forms, it may look a lot worse on Microsoft's end.

    For now the best we can do is open problems, add information and try what others come up with.

    I can't help but suspect that at some point the folks at AMD may become as unhappy as we are.

    Same problem with AMD Athlon 3200+ They just killed my computer while I was away.

    Didin't have any successful rollback.

    Do you think there is any chance of repairing Windows and not reinstalling it?
