Microsoft started deploying microcode updates to some of Intel's older Core, Pentium, and Celeron processor generations through Windows Update. The latest Cumulative Update packages chronicled under "KB4497165" apply to machines running Intel's 4th generation Core "Haswell" processors, and low-power Pentium and Celeron chips based on "Apollo Lake," "Gemini Lake," "Valley View," and "Cherry View" microarchitectures.
The microcode update provides firmware-level hardening against four major variants of the MDS class of security vulnerabilities, namely CVE-2019-11091 (MDS Uncacheable Memory), CVE-2018-12126 (Microarchitectural Store Buffer Data Sampling), CVE-2018-12127 (Microarchitectural Load Port Data Sampling), and CVE-2018-12130 (Microarchitectural Fill Buffer Data Sampling).
