Boy people really do not like change do they? I've been using Win10 since release and it by far surpasses Win7 both in performance and UI along with so many other things.
Overall Microsoft don't make this stuff for free and cannot continue supporting ageing software forever. Other vendors do the same Google, Apple etc they push and force upgrades in fact even more heavily than Microsoft yet Microsoft get slammed for it. 10 years Win7 has been supported and that is a good amount of time for an OS that you may have purchased through OEM or separately back then.
I loved Win7 too in its day but its had its time and it's time to let go as change is inevitable in tech as in life.
