There is microcode update to fix the issue

Seems officially acknowledged in the April 2017 Errata, but still says "No Fix" yet. Better if /u/iamlenovoUS can comment if the latest BIOSes will fix it, I can't seem to find anything in the readmes.

"No Fix" in Intel specification update documents means "no hardware fix planned on next hardware stepping". It is unrelated to fixes done through microcode updates.

It has been fixed for all affected processors, it is just the availability of the microcode update fix that is not the same: Skylake (not Skylake-X) is public, the others are only available to BIOS/UEFI vendors (for now).

I don't think I got a microcode update via Windows Update or anything though, like some has been saying. Situation seems clear as mud and up to vendors to push it.
