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 ”).
