Win7 also had issues, but it felt much more usable for professional use
What issues did you have? I remember it only being light on resources, stable, and aesthetically pleasing. The UI introduced snap-to-edge, which was such a game changer at the time and really makes Windows versions before it feel archaic in comparison. It was the last Windows version before the layout of settings stopped making sense.
I’m sure this is just rose-tinted glasses so I might be ignoring some issues, but I can’t recall anything in particular.
