In my experience Vista was the worst version of windows ever released. Glassy stuff looked cool but was a huge power hog. Thank god you could turn it off. And 10 feel horrible too (dont upgrade). It doesnt let you “ungroup” windows on the task bar. I prefer them separate and they just removed the option. Why? It was already there. It is a common preference of users. Best windows in my opinion was xp and 7.
