works on various systems here:

microcode updated early to revision 0x23, date = 2017-11-20 previous was 0x22 from January

I have a question:

Does this microcode update negate the need for a firmware update? And if so, why do Windows machines require firmware updates if a microcode update would suffice?

Thank you.

So yes, and no. This is pushing the same microcode that a firmware update would. Obviously firmware can load the microcode earlier, so that is a better solution. As for Windows, I have no idea how they handle microcode loads, certainly they are capable of something similar, but this microcode was literally released about 30 minutes before the package hit koji. I got a heads up from Intel and passed it along. The date is 11-20, so it has probably been available for hardware vendors to do QA and push firmware updates for a while now. Certainly Fedora users would have gotten it sooner if a firmware update was available from their vendor.

works for me

Works, but as already noted by Intel, no new revision for 1st, 2nd and many 3rd gen Core i(X). Fine by me, no Intel anymore :-/
