In essence: yes.

Python's support for Windows is outlined in PEP 11:


which establishes that Python drops support for a Windows platform when 
Microsoft does. WinXP (somewhat noisily) finished support last year:


while Server 2003 -- more quietly; I had to go and look -- came out of 
extended support this month:


Since Python 3.5 will come out after both of those platforms have 
finished support, there's no guarantee that it will run without error on 
those systems.

Obviously, all earlier releases of Python -- including the 
long-term-supported 2.7 should continue to work. Any otherwise 
undocumented failure to work on older platforms should be raised as a bug.
