Respectfully disagree. NT/Win2000 was the peak as it was before they added all the DRM/phone home junk. It ran fast, in fact diablo ran smoother on it than on the win 98 partition I had at the time. Granted some programs failed because they were doing things memory wise they should not been doing...
2K was amazing compared to 98, but 7 has a number of QoL and tech improvments that I'd have a hard time giving up, and it's easier to make 7 better behaved than to bring 2K into the modern era.
