The AMD-compatible Spectre fix for Windows 10 is now live and being distributed through Windows Update.
When the Meltdown/Spectre vulnerabilities first surfaced, Microsoft was quick to respond by rolling out software mitigations in its operating systems. Unfortunately, the fixes in Windows 10 had an unintended consequence for some older AMD CPUs, making them unbootable. Microsoft stopped issuing the update to affected AMD systems.
Users should note that this update only applies to older AMD CPUs. Ryzen and Threadripper-based systems weren’t gated from receiving the original patch. Also, this patch has no relation to the recently announced optional Windows patch that disables Spectre Variant 2 fixes for Intel CPUs
