Important
This update is a standalone update that is targeted for Windows 10, version 1803 (Windows 10 April 2018 Update) and Windows Server, version 1803 (Server Core). 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. By default, this mitigation is turned off for Spectre Variant 4 (CVE-2018-3639: "Speculative Store Bypass (SSB)"). Please make sure that mitigation against Spectre Variant 4 (CVE-2018-3639: "Speculative Store Bypass (SSB)") is enabled for Windows Client and Windows Server through the registry settings that are documented in the following articles:
- Windows client guidance for IT Pros to protect against speculative execution side-channel vulnerabilities
- Windows Server guidance to protect against speculative execution side-channel vulnerabilities
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.
