Overview
Microsoft has now resumed updating all AMD-based devices with the Windows operating system security update to help protect against the chipset vulnerabilities known as Spectre and Meltdown. Microsoft worked with AMD to resolve update blocks on a small subset of older AMD processors (that were previously blocked to avoid users getting into an unbootable state after installation of recent Windows operating system security updates). For AMD device-specific information, please see this AMD Security Advisory.
