IShellLinkDual is the same as IShellLink. That came from my shell32.dll.
Although my OS is a little strange and is in need of reinstalling. Dual
means it's a dual interface i.e early bound rather than a dispatch interface
which is otherwise known as an automation interface which is late bound via
IDispatch.

No you had that as a comment.

They are the same thing.
