Unlike microcode updates, which are rolled out by the board manufacturers for the BIOS or UEFI, Windows loads the new microcode on system startup.&nbsp; <\/p>\n<p>After installing Windows 10 April Update (V1803), users quickly noticed that the Spectre V2 microcode was not included (see <a href=\"https:\/\/borncity.com\/win\/2018\/05\/04\/windows-10-april-update-bugs-and-issues\/\">Windows 10 April Update: Bugs and Issues<\/a>). For Patchday (May 8, 2018), only special microcode updates for AMD CPUs for Windows 10 version 1607 were rolled out (see <a href=\"https:\/\/borncity.com\/win\/2018\/05\/09\/windows-10-security-updates-may-8-2018\/\">Windows 10 security updates May 8, 2018<\/a>). <\/p>\n<p>Update <a href=\"https:\/\/support.microsoft.com\/en-us\/help\/4100347\/intel-microcode-updates-for-windows-10-version-1803-and-windows-server\" target=\"_blank\" rel=\"noopener\">KB4100347<\/a>, released on May 15, 2018, is the microcode update to mitigate the Specte V2 vulnerability (CVE 2017-5715 [\"Branch Target Injection\"]). It is available for Windows Server version 1803 and for Windows 10 version 1803 clients. Please note, however, that the update only applies to certain CPUs listed in article KB4100347.
