You would have to recersively call GetClassName(), GetWindowLong(), etc to
gather information about the window and all of its child windows, and then
use CreateWindowEx() to recursively create and position new instances of
each one.  Even then, that only duplcates the parent/child hierarchy, but
there is no guarantee that the internal data of the windows can be copied so
that the clones actually function properly.

Just having the HWND is not enough to guarantee that you can clone
everything that matters.

That is all you can do.
