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

Anonymous

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?

Ciao Snoopy,

may you explain how you have "changed update polices so Windows will download updates with notification but not install them until YOU approve them"?

Thanks,

Angelo.

Sorry, my description was not correct of what policy I set. I set it to notify me when an update was ready to be downloaded and installed. I can choose to not download it.

This is for Win 10 pro, not sure whether it will work in other versions.

Group Policy Editor

    Open the Run command (Win + R), in it type: gpedit.msc and press enter.

    Navigate to: Computer Configuration -> Administrative Templates -> Windows Components -> Windows Update.

    Open this and change the Configure Automatic Updates setting to '2 - Notify for download and notify for install'

The computer I was fixing only has "Notify to download and auto install", "Auto download and notify to install" and "Let administrator decide action" (or something like that). In update and security it says that "Some settings are managed by your organization". I only noticed that when I did a restore from a restore point. I think that might be why I don't have 'Notify to download and notify to install". Hmm

Identical issue (Windows logo only on boot) experienced on an AMD Athlon 64 X2 5600+, just after installation of KB4056892. Fortunately a system restore point was created prior to installation, which I could roll back to.

Have used the "Show or hide updates" troubleshooter package (available via https://support.microsoft.com/en-gb/help/3183922/how-to-temporarily-prevent-a-windows-update-from-reinstalling-in-windo (URL is complete, even though it appears truncated!) to temporarily disable further attempts at installing this update, until MS resolve the issue...
