Microsoft has resumed updating the majority of AMD devices with the Windows operating system security update to help protect against the chipset vulnerabilities known as Spectre and Meltdown.
A small subset of older AMD processors remain blocked to avoid users getting into an unbootable state after installation of recent Windows operating system security updates. Microsoft is working with AMD to resolve this issue and should resume Windows OS security updates to this subset of AMD processors via Windows Update and WSUS by next week. For AMD device-specific information please refer to AMD’s Security Advisory.
Microsoft has temporarily paused sending the following Windows operating system updates to this subset of older AMD processors:
