public class Registry
extends java.lang.Object

This code is a refactored version of some code floating around at stackoverflow, supposedly orinally written by david@stackoverflow(656963), enhanced by petrucio@stackoverflow(828681) to add (some) support for 32/64 bit WOW awareness. Modified to be more OOP, give proper error messages, properly close all handles and beautified the API by p.bechtel@oashi.com
