I can't think of the "why", but I never got to tinker with 7. I think I jumped from XP to 8. I remember I had installed "Longhorn" for fun on a secondary PC, but I stayed at 8 and 8.1 (with ClassicShell) for many many years. I only jumped to 10 when I realized that my 2015 laptop can live and thrive even today with Win10Pro due to their amazing RAM/CPU performance (with some heavy fine-tuning)(black viper!![0],[1] even if the pages no longer exist I still keep them on my favorites!!)

It was said/suggested on SecurityNow from someone in the audience that "hey why don't you use Windows 20YY Server? It's like your home/pro Windows but without the shitware" (loosely reworded by me)
