Back when Vista was new I had an Dell XPS running that OS. That was before I built my own systems. Anyway, that PC must have generated hundred of errors report over it's two year life. Maybe it helped make 7 the stable dream that it is today. Yes, I really like 7 Pro 64 bit.
Looking way back, to XP. I always hated that OS. Not sure why is generally held in high regard.
Also did the Win 8 consumer trials. And I really hate it.
