Win2K was my favorite as well. The transparency was tasteful. Everything worked and for the most part didn’t crash. Many (most?) games worked. It ran great on a PIII 600mhz. Everything good about NT4 was better and most of the consumer friendly stuff starting to take shape. The disc was even gorgeous. Peak MS design and engineering.
I love me some Windows 2000 but when I got to XP I was running it with a BeOS theme. My peak of windows ux may be around Windows 10 Beta 1 - combined 7/8/10 transparent and start menu and was super fast. That said beta 1 of Win11 was also super fast so that makes me wonder what they broke under the hood.
Yep, favorite version of Windows ever. Even with Windows 7 and XP I switched the settings back so it looked like Win2K.
Win2k was the last one I was excited about.
