Windows 2000 was a good operating system by any measure. It was rock solid, capable, well-supported, could scale from desktop to large enterprise deployments and everything in between, reasonably secure compared to their previous operating systems, etc. I never did like Microsoft operating systems, but Windows 2000 was actually good. It was a breath of fresh air at the time. We had NT 4, which was stable and reliable, but was limited by a lack of DirectX and became cumbersome in large deployments. Then we had Windows 95/98/ME, which was the garbage that crashed all the time.
The whole video does.
