Microsoft has not told anything about the patches for Spectre V4 vulnerability whether they have integrated the microcode update.

Earlier in January 2018, they sent the updates for Windows 10 1511 but it seems that they didn’t imagine the seriousness of the threat.

KB4090007, KB4091663, KB4091664, and KB4091666 also targeted the same threat and arrived in March 2018. Unfortunately, the patches  (starting versions) did not support all the processors that Intel created microcode updates for.

However, the Microcode updates from Intel protects multiple CPU but Microsoft didn’t include them in Windows update (WSUS).

KB4090007, KB4091663, KB4091664, KB4091666 worth welcome to support  4 Windows 10 versions, still several editions are waiting. Precaution is better than cure so they must release the Microcode updates for remaining versions.

Microsoft is sending the patches to fight against Spectre and Meltdown vulnerability one after another so the users who haven’t got the updates yet must keep checking. The updates are uploaded to Microsoft Update Catalog, visit the site and protect your processor.
