I have two PC affected by this bug an Athlon X2 64 4200+(Dell Dimension E521) and a Turion X2 64 (HP 6735s laptop). The same symptoms, using Windows 10 Pro 64. I have paused automatic updates for 35 days. I expect Microsoft to fix this huge problem as soon as possible.
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?

2018-01-07T20:24:36+00:00 I don't have any restore points and all other options (going back to the old version cause I still have Windows.old) don't work. I don't want to try to reset it yet. I'm trying to find a way to somehow uninstall the update using cmd from recovery .

2018-01-07T19:18:42+00:00 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?
On my machine, I had to power cycle twice when the machine froze on the blue Windows logo screen before it started 'Automatic Recovery' mode and reverted to the previous build. You then have to uninstall the KB4056892 update, and pause updates (Windows 10 Pro) to stop it trying to reinstall the KB4056892 update at the next boot.
Hope this helps,
Dave.
