Right-click "Register" option for ocx's and dll's

[seaweed]

Does anyone know how you add the "Register" option to the popup menu that appears when you right-click on a .dll or .ocx file?

My computer at work has it, but not at home. Couldn't find the option to add it in TweakUI, either.

I'm running Windows 2000 (SP1).

Thanks in advance!!!
