Meltdown and Spectre: Microsoft’s bug fix reportedly crocking AMD PCs

Ironically, AMD CPUs were immune to Meltdown, but susceptible to Spectre, however the patch has now cropped a new issue.

And it gets worse. After Microsoft recently confirmed that it is mitigating the Meltdown vulnerability with automatic updates, reports have fallen in that Microsoft’s fix for the bug, may be crocking AMD-powered PCs.

First reported on answers.microsoft.com, users have shared a bunch of cases in which Security Update for Windows KB4056892, Redmond’s Meltdown/Spectre patch, leaves some AMD PCs with the Windows 7 or 10 startup logo and not much more.

Users complained that some Athlon-powered machines, which were earlier in perfect working order, were bricked after the patch was installed. It was reported that, the patch doesn’t create a recovery point, so rollback is little use, and the machines emerge from a patch in a state from which rollback is sometimes not accessible.

Some say that even re-installing Windows 10 doesn’t help. Others have been able to do so, only to have their machines quickly download and install the problematic patch all over again.

This means that users who suffer from the patch issue will therefore need to disable Windows Update, as their only option. Keeping the machine off networks seems a helpful precaution. Ironically, AMD CPUs were immune to Meltdown but susceptible to Spectre, but the silver lining in that cloud has been dirtied by the patch problem.
