I work in IT, I guess I'm too much of a youngin to remember the non-NT days (only used Macs at home, first PC experience was XP). I'm surprised at the hate for Win 10. Win 8 was a much bigger UI disaster, especially with Sever 2012 using the same UI for some inexplicable reason. However Win 7 was bloated and Win 8 made a host of changes that made most of my PCs perform better, start-up faster, etc. Win 10 functionally is the best of both. Of course they stupidly fractured the settings and moved in more of an Apple direction with how they force certain features on you, but the underlying architecture was great.

People shit on Vista, but most people disregard the fact that Windows 7 is basically Vista SP2. That really seems to be MS's MO. Improve the architecture and basically beta test it for an entire release cycle, then actually make something useful.
