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?

    Arrrg, yes it is a PITA boomerang. Hanging, unbootable Windows 10. Removed KB4056892 using dism, was able to boot again but did not disable Windows Updates because KB4073707 *claimed* to have paused the updates for affected AMD processors. And now... again crashing / hanging with unbootable Windows 10. This is AMD 5050e BTW. It’s just sad.

    The same thing is happening to me, except that I have an older Intel Core i7-2600K processor!

    After the update, my PC reports that the boot drive is inaccessible and then it gets stuck in a endless boot loop as Windows tries to repair it, but fails. The only way out is to restore to a point before the update!

    Hi LordGrimm66,

    I downloaded the file wushowhide as suggested by Gianni1962 (see earlier) and it has inhibited the specific update - no restart problems, so far.

    Worth a try ( I had 8 restart failures before this fix)

    Regards,

    Derek

    Hi Gianni1962,

    Many thanks for prompt response - downloaded the file and run it  successfully. Have restarted several times without hanging.

    I hope inhibiting it won't impact on future updates.  

    You're a star. Cheers

    Derek
