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?

    for Windows 10 1607 you have to install KB4057142 to fix the boot failure.

    So just for my understanding, you're suggesting that I install KB4057142 while currently using the Win 10 1607 build, then attempt to re-install build 1709 and hopefully that will eliminate the boot failure issue(s)?

    I am wondering if problems with these AMD "A" series processors ( example knight1fox3 )  should be addresses in a different thread.  They are something of a different animal as they have an internal graphics adapter.

    From wikipedia........

    Steamroller architecture (2014): Kaveri

    Main article: Steamroller (microarchitecture)

    • Steamroller-based CPU with 2–4 cores[62]
    • Graphics Core Next 2nd Gen-based GPU with 192–512 shader processors[63]
    • 15–95 W thermal design power[62][63]
    • Fastest mobile processor of this series: AMD FX-7600P (35 W)
    • Fastest desktop processor of this series: AMD A10-7850K (95 W)
    • Socket FM2+ and Socket FP3[62]
    • Target segment desktop and mobile
    • Heterogeneous System Architecture-enabled zero-copying through pointer passing

    The third generation of the platform, codenamed Kaveri, was partly released on January 14, 2014.[64] Kaveri contains up to four Steamroller CPU cores clocked to 3.9 GHz with a turbo mode of 4.1 GHz, up to a 512-core Graphics Core Next GPU, two decode units per module instead of one (which allows each core to decode four instructions per cycle instead of two), AMD TrueAudio,[65] Mantle API,[66] an on-chip ARM Cortex-A5 MPCore,[67] and will release with a new socket, FM2+.[68] Ian Cutress and Rahul Garg of Anandtech asserted that Kaveri represented the unified system-on-a-chip realisation of AMD's acquisition of ATI. The performance of the 45 W A8-7600 Kaveri APU was found to be similar to that of the 100 W Richland part, leading to the claim that AMD made significant improvements in on-die graphics performance per watt;[62] however, CPU performance was found to lag behind similarly-specified Intel processors, a lag that was unlikely to be resolved in the Bulldozer family APUs.[62] The A8-7600 component was delayed from a Q1 launch to an H1 launch because the Steamroller architecture components were allegedly did not scale well at higher clock speeds.

    Although "fx" series vintage, I wonder if these "A" series CPUs might have slipped through a crack.

    Interesting. In that case, then I'm experiencing issues related to a newerWindows 10 version. 1607 works just fine and updates accordingly. It's 1709 that seems to have issues.

    KB4056892 is not bundled with 1709, seems you are experiencing other issue related with an older Windows 10 version.
