Start by dropping an instance onto a form.  It should appear down at the bottom in the "components" region of the form. 

Then, simply set the RegistryKey property on it.  This needs to be the full path to the registry key like this: "HKEY_LOCAL_MACHINE\Software\Ricardo"

Then, use the methods on the component to get/set the values within that registry key.  It essentially allows to create/read registry values with a single line of code rather than having to use the objects within the Microsoft.Win32 namespace.

Thanks...
