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?

    Since u have pro then follow the steps to delay updates. You may need to disconnect the internet to be sure the update does not download until set to dekay.

    Try advanced repair. Check fir a system restore point.  If you are lucky enough to have one or u knew to enable then u can restore. After that it is repair keeping files but lose apps.

    Finally made some progress. I wasn't able to boot into recovery mode for some reason so I had to use an update disc. It got half way through and said there was an error and couldn't continue installing (I think it was because I was using the Home version to reinstall the Pro version but not sure). It then started to revert back to a previous version. After that it booted ok and I ran the hide/show app and successfully blocked the troublesome update. I restarted right after I blocked it just to make sure but it started to initialize the download, I closed the window and when I checked on it again after a couple of minutes it was gone. The computer is now up to date minus the KB4056892 update. Going to make a restore point after I make sure everything else is updated. WOOHOO!

    You can use media creation tool and get into windows recovery.  Use system restore.
