Let's go again: Microsoft has released new Intel microcode updates in Windows 10 that replace or update previous updates to Specter variants.
Updates are available for Windows 10 in versions 1803, 1709, 1703, 1607 and 1507. Currently only available through the Microsoft Update Catalog.
Updates KB4346084, KB4346085, KB4346086, KB4346087, KB4346087, KB4346087, KB4346087 and KB4346088 protect against various attacks that target vulnerabilities in Intel processors and affect most of them.
Tip: If you want to know if your computer is affected you can try the Intel processor with the free tool InSpectre for Windows.
Microsoft says for updates:
Intel recently announced that it has completed its validation and launched microcodes for the latest CPUs that protect the Specter Variant 3a (CVE-2018-3640: “RSRE)”, the Specter Variant 4 (CVE-2018 -3639: Bypass storage stores (SSB) ”), L1TF (CVE-2018-3615, CVE-2018-3646:“ L1 Terminal Fault ”).
In short, the new update adds protection for the Specter 3a and 4 variants and includes previous updates released by Intel and Microsoft.
