So a full 7 months after CoffeeLake release, how long do would anyone wish to wait on someone's hack of the OS and/or drivers to hope that Win7 works, until some security update breaks it, etc....?
I liked Win7 too, and, yes, Win10 did suck the first several months it was out in Beta, but, it can be tweaked to be VERY similar to Win7, but with a prominent search/launch bar.
While MS is still allegedly letting people activate Win10 using Win7 product keys, I'd recommend going that route (if possible) while they are still being generous, as that should have ended last summer.
