Microsoft Releases Patches for AMD CPUs Broken by Original Meltdown and Spectre Fixes

Written by Jon Sutton on Sun, Jan 21, 2018 11:59 AM

Microsoft has issued a pair of updates that fix the already broken Meltdown and Spectre patches that caused a number of older AMD processors to Blue Screen. Well, sort of. The KB 4073578 and KB 4073576 updates are available for Windows 7 and Windows 8.1 users respectively, and there’s no mention of a Windows 10 update whatsoever. All the info we have is that these "Unbootable state for AMD devices".

In a further slice of confusion, the updates don’t replace the previously released updates, so if you’re already suffering from an unbootable system then you’re going to have to work out how the heck to get these patches installed on top. Your best bet here is to use Windows recovery to rewind to a previous Windows installation, then auto-update through Windows to the latest version, and then grab these new fixes. It’s also a little unclear whether you need to install the broken update first and then install this secondary update on top.

Just to make things a little more fiddly, these updates aren’t available through Windows Update either and need to be downloaded and installed manually. There are no official instructions provided on how to do this, nor are there any actual details as to what these patches do. They’ve sort of just been farted out into the ether and AMD owners have been left to figure it out for themselves.

CPUs affected by this include AMD Opteron, AMD Athlon, and Turion X2 Ultra processors, so if you’ve got any of these then it’s recommended you grab the appropriate fix and protect yourself from Meltdown and Spectre vulnerability.

If you happen to have one of these older CPUs then be sure to let us know below if you have any luck with these updates!

Motorola 6809 FTW! xD Seriously though.... I've have many AMD CPUs, ranging from the old K6-2 to the Athlon 64 X2(ALL of which I still currently own AND use)..... my next CPU will likely be AMD as well.
