Microsoft’s software update for Windows which is Microsoft’s first attempt at a “patch” for the Meltdown and Spectre security flaws in x86-64x processors has caused a large number of computers with AMD processors to crash.
The update is bricking some AMD PCs by not allowing the computer to re-boot. After several failed re-boots, most devices will rollback the last software update.
Removing the update allows these AMD PCs to boot up again, but the automatic update feature of Windows will automatically download the security update again, starting the cycle over again. Frustrating consumers.
In a statement, AMD acknowledged the issue but stated it is primarily a problem with older generation processors.
The statement noted that
AMD and Microsoft have been working on an update to resolve the issue and expect it to begin rolling out again for those impacted shortly.”
Unlike AMD, Microsoft has not publicly responded to the apparent incompatibility of the update with older AMD processors.
It is believed that the AMD processors are not vulnerable to the Meltdown attack but are susceptible to the Spectre attacks.
This update was intended to provide a patch for some of the Spectre attacks, although firmware and/or hardware updates are also required to patch some of the Spectre vulnerabilities.
