*Rolled back to microcode updates related to Spectre Variant 3a (CVE-2018-3640: "Rogue System Register Read (RSRE)"), Spectre Variant 4 (CVE-2018-3639: "Speculative Store Bypass (SSB)"), and L1TF (CVE-2018-3620, CVE-2018-3646: "L1 Terminal Fault")

Important

This update is a standalone update that is targeted at Windows 10, version 1803 and Windows Server 2016, version 1803. This update also includes Intel microcode updates that were already released for these operating systems at the time of release to manufacturing (RTM). We will offer additional microcode updates from Intel through this article for these operating systems as they become available to Microsoft. Use the registry settings as described in the Windows client and Windows Server KB articles. (By default, these registry settings are enabled for Windows Client OS editions, but disabled by default for Windows Server OS editions.)

Consult with your device manufacturer and Intel through their websites regarding their microcode recommendation for your device before you apply this update to your device.
