Ouch! Microsoft's Spectre security update bricks some AMD-powered PCs

Bad news if you own a Windows PC that has an AMD CPU at its heart and haven’t yet received a Microsoft security patch for Spectre and Meltdown - you may have to wait a bit longer.

Bad news if you own a Windows PC that has an AMD CPU at its heart and have received a security patch from Microsoft - you may have had your computer shagged.

In a support advisory, Microsoft says it has temporarily halted sending out Windows security updates to devices containing AMD processors, after customer complaints:

Microsoft has reports of customers with some AMD devices getting into an unbootable state after installing recent Windows operating system security updates. After investigating, Microsoft has determined that some AMD chipsets do not conform to the documentation previously provided to Microsoft to develop the Windows operating system mitigations to protect against the chipset vulnerabilities known as Spectre and Meltdown.

According to reports, users with affected hardware found that after the security patch was installed they found themselves facing the Windows boot-up screen, and then nothing more…

Ouch! That’s not good.

Microsoft and its customers have been having a rough time mitigating against the Spectre and Meltdown threats, after it was found that some anti-virus products were incompatible with the fixes.

    A very tricky issue. I’m trying to stay on top of it in order to send my colleagues helpful information. It will be interesting to see an actual exploit of this problem. For now, mitigation efforts may be worse than the problem itself.
