Microsoft CEO Satya Nadella. Stephen Lam/Stringer Microsoft is pausing Spectre- and Meltdown-related security patches for AMD machines after reports of computers not booting up, as first written up by The Verge.

Users took to the company's support forums en masse, with the bulk of complaints coming from users with Windows machines running on AMD chips.

The company has acknowledged the issue, and blamed it on AMD and its documentation: "Microsoft has reports of customers with some AMD devices getting into an unbootable state after installing recent Windows operating system security updates," Microsoft's post reads.

"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."

Customers that found their computers unable to boot following the update must now visit Microsoft's support site to restore their machine, while both Microsoft and AMD work to resume the availability of patch-equipped software updates.
