How do I walk recursively windows registry in lua?

I'm coming from linux land so bear with me please.

I want to walk through windows registry recursively. All I've managed to do so far get the values of individual keys

> require 'luacom'> sh = luacom.CreateObject "WScript.Shell"> = sh:RegRead "HKCU\\Console\\ColorTable01"8388608

yet see no way to iterate registry nodes...
