It goes back even further than that. I repeated it for Vista, during the Beta testing period, about four years ago. I think I copied it from the technet forums. It was also featured in an article in WinVistaClub about two years ago. It is nothing mind shattering. Most of the commands are availble in the various sections of the Control panel, and can also be typed direct into help and support with the same result. But, it is undoubtably a better alternative to the default conontrol panel.
I have always kept it for reinsertion in subsequent installs. fwiw, I like its appearance in small icon view.

There have been suggestions that this can cause 64 Bit OS's to crash. I only use 64 Bit and have not had this bad experience (Yet!)
