Licensing of Active Template Library

  atl, c++, licensing, wtl

I would like to build some GUI with WTL which is open source and licensed under the Microsoft Public License. As far as I understand it is tightly coupled to the Windows Active Template Library (ATL). ATL is normally shipped with Visual Studio or some redistributable Package. Unfortunately I found no information about the license of ATL. In header files like atlbase.h it is only noted that Microsoft holds all copyrights and further license information can be found when looking for the Active Template Library Product. But such a Produkt does not exists (at least no such product can be found on the microsoft homepage). So under which license terms is ATL published / delivered ?
