    A number of AMD PC users say they can't boot after installing Microsoft's Windows 10 Meltdown-Spectre patch.

    Microsoft's Windows patch for the Meltdown and Spectre attack methods is reportedly causing problems for users with AMD Athlon CPUs.

    According to a number of complaints on Microsoft's community forum, the problems are appearing on Athlon systems that received the update for the Windows 10 Fall Creators Update, labelled KB4056892.

    The initial reporter said after installing the update the PC only displayed the Windows logo and otherwise failed to boot.
    The update was delivered through Windows Update.

    "After several failed boots [it does] a rollback and [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," wrote the reporter.

    It's not clear how widespread this issue is, but the reporter noted that the CPU involved is "quite pre-historic", specifically the AMD Athlon X2 6000+, which was released a decade ago.
    Others who report the same issue are also using older AMD chips.

    It's also not certain that Microsoft's patches for the Meltdown and Spectre attacks are the actual cause of the problems, given KB4056892 contains much more than these specific security fixes.

    Microsoft hasn't responded specifically to the reports yet, instead issuing a general statement relating to the Meltdown and Spectre problem.

    AMD chips aren't vulnerable to the Meltdown attack, but operating system updates could address one of the Spectre attacks it was vulnerable to.

    AMD said there was a "near zero risk" its chips could be exploited by the second Spectre attack, which required firmware updates from OEMs containing CPU fixes such as Intel's IBRS microcode fix or Google's Retpoline software fix.
