Microsoft has now made Intel firmware update KB4090007 available for the Windows 10 version 1709 aka Fall Creators update. This is a standalone update that can be downloaded form the Microsoft update catalogue. This update is available only for some Skylake devices initially and will be broadly available in coming days.

Today, Microsoft will make available Intel microcode updates, initially for some Skylake devices running the most broadly installed version of Windows 10 — the Windows 10 Fall Creators Update — through the Microsoft Update Catalog, KB4090007. We will offer additional microcode updates from Intel as they become available to Microsoft. We will continue to work with chipset and device makers as they offer more vulnerability mitigations.1
