The initial issue was some system functions that are new in Vista.  Then 
came MS's new-with-Win10 toolset that does not support XP.

As I explained in another message, it was the other way around, in a 
sense.  As long as MS supported XP, Windows CPython devs either 
refrained from using new not-in-xp features or maintained old 
workarounds.  The has been more or less the same policy for other 
versions of Windows.
