Well windows 10 will go out of support in 4 years. A brand new build using a 1600AF isnt supported, neither is a 5950x, both systems have WAY longer then 4 years remaining. This is palcing arbitrary time limits on hardware that should not exist.
I think you A) forgot that MS is still supporting those 1.4 GHz celeron netbooks, it's the 8 core 16 thread 5960x systems they are cutting out of the loop, so that's not going to fix anything, and B) cutting slower hardware out does not make for a faster, nor more convenient, system. The first is the opposite, as raising the hardware bar excuses lazy programming and optimizations, and the latter is mutually exclusive.
MS has had 10 years to move the control panel to the settings app. 10 years. Supporting old CPUs did not prevent them from finishing this task. Supporting old CPUs did not cause the myriad of nasty bugs that MS has been haphazardly patching the last 3 years, like printnightmare. CPU bugs like spectre and meltdown were affecting brand new hardware.
MS is in shambles right now shoveling beta half baked software onto consumers. Anyone who thinks that excluding older hardware is going to get MS's rear end in gear and actually fix their borked OS is delusional, and totally ignorant of how lazy MS has been since 7.
