Microsoft releases new Intel microcode updates for all supported Windows 10 versions

Microsoft has released new Intel microcode updates for all supported Windows 10 versions that revise mitigation for four Microarchitectural Data Sampling (MDS) threats. The updates are being made available via the Update Catalog for all users. However, users running certain versions of Intel’s processors will receive the updates through Windows Update.

Microcode updates are aimed at patching hardware vulnerabilities that require not only a software fix, but also firmware level changes. The best examples of such updates are the Spectre and Meltdown vulnerabilities that required multiple software and microcode updates. The recent updates target multiple processor generations – across desktops and laptops.

The following KB articles for the respective Windows 10 versions provide more information on the list of processors being patched:
