Windows 7 and processor support confusion (Haswell, SkyLake, Kaby Lake, etc)

Can someone explain what will happen if I try to run windows 7 on Kaby Lake? Will my computer explode? I understand that Windows 7 won't be able to use the new Speed Shift and Turbo Boost 3.0 technology, but will Windows 7 run at all? Also, I see after July 2018 critical updates will only be addressed for systems running on Skylake. So does this mean if I am running Windows 7 on Haswell I'm out of luck, no security updates for me?

Kaby Lake hasn't been mentioned officially - the document is about Skylake. Haswell is fully supported.

Microsoft has backtracked a bit and certainly Skylake will work. There has not been a definitive word on Kaby Lake at this point and as noted, it is not out for a while yet.

Why do you need to run Windows 7 on a new machine. Windows 7 is now old and on the downslope to dying out.

If (say) Kaby Lake will not run Windows 7, nothing will happen - it just will not install.

Haswell comes before Skylake and Windows 7 will get updates on it.
