After installation of KB4056892 boot failure, after roll-back error 0x800f0845

Question

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?

Answer 1

I find that having a boot menu to break up the auto restarts helps clarify when stuff has gone wrong.  Also it gives the possibility of looking at things earlier than would be possible otherwise. 

bcdedit  /set  {bootmgr}  DisplayBootMenu  "yes"

Another box, this time AMD Athlon 64 X2 6400+ BBE, Asus MB, the same symptoms - Windows logo, no animation, hard lockup in very early stage of the boot. This machine also have some custom junction links - from the past I know that the installer cannot run transactions over junctions pointing to different physical disks which could result in such kind of redirection errors, but I am becoming skeptical that it's the source of this problem. I am going to dig through the logs tomorrow according to previous hints.

I am curious what's the 'err' command/script you used? It looks quite handy :)

I am also having this issue on my AMD Althlon 64 x2 5000+. I've tried reinstalling windows and installing the update with no additional software installed and the issue is still there. Very frustrating issue! It’s an old computer but it’s still good. Would appreciate MS fixing this issue, it was working fine before this update.

Weird, I'm on 17063 with a  AMD Athlon 64 X2 5600+ and it works fine.
