Inno setup registry

What can I add to the win registry so that the explorer context menu, when you right click on a file, gains an entry that calls "\path\to\exe" "path\to\this\file\you\right\clicked\on"? If that's possible to be done in Inno setup easily, could you possibly provide me with some examples? (As well as get rid of the registry key upon uninstall)

Thanks.
