Microcode updates for spectre v3a, 4 and L1TF

[Fho00]

I just checked the list with supported cpus for the latest microcode update and i cant find the Intel Core i7-4790K in the list.

Does that mean it is not supported with this update and ist there going to be a different microcode update for this cpu? I also noticed that i dont have any of the kb updates installed on my other machines, do they get installed with windows update automatically?

This is the list i checked:

I dont see a list of impacted products on that site but i guess that all recent intel cpus are affected, so that shouldnt matter.

Is the microcode update that is delivered with KB4465065 compatible with a i7-4790k intel cpu?
