Windows 2000 was the last version where Dave Cutler was fully in charge of Windows.

Things started going downhill after that.

Windows 2000 was a bug riddled, poorly architected punching bag for malware.

Things definitely went up-hill AFTER Windows 2000.

What on earth would cause someone to say Windows 2000 was a good release? It wasn't even a good release when it came out, and it definitely didn't stand the test of time.
