What I learned is this:

- support for multiple DDE servers was removed; this was apparently "implemented via some low-level hacks that were incompatible with DEP prevention and 64-bit".

- Because of this, I think the canonical usage:

>>> import dde
>>> server = dde.CreateServer()
>>> server.Create('TestClient')

does not work (because this implies the ability to create multiple Servers?) (*)

- The following usage (is win32ui needed her? not checked)

>>> import win32ui, dde
>>> dde.CreateServer().Create('TestClient')

Should work. HOWEVER: if you try it from eg. within PythonWin, it will fail. This is because PythonWin uses the one available server. so you will get different results if you try this from within pythonwin, and at the python prompt.

- you can disable pythonwin's use of DDE by starting it up with '/nodde'

(*) I haven't checked this at the command line – it might fail because I was trying it within pythonwin.
