Hey, someone else was going to do it if I didn't!
Fun fact: Win2K came first (released Feb 2000 against ME's Sept 2000). You probably just remember the move going in that direction because WinME was the OS equivalent of opening "Dr." Hitler's Abortionarium in Tel Aviv.They base each new OS on the last until some major change is required, like the move from WinME to Win2k.
