Windows Vista SP2 is out of support by the time that Python 3.7 releases (see PEP 0537 and [1]), so we should do the following tasks:

*  update the definition of Py_WINVER in PC/pyconfig.h to 0x0601 _WIN32_WINNT_WIN7
* remove any dynamic API imports that are not required on Win7 (I don't think there are many, if any)
* remove pre-Win7 supportedOS elements from PC/python.manifest
* block Windows Vista in the installer

We may also be able to take advantage of new flags, particularly related to security (I think LoadLibrary[Ex] got new flags).

If there's anything else we need to do, post it here so we don't forget.

How certain are you that Vista support will actually end?

Other things: assuming reasonable certainty, could the 3.6 installer say "This is the last version that will run on Vista!"?

Only as certain as anyone else in the general public - I don't have any special information besides what has been published.

Since it's been published for the specific intent of helping 3rd parties plan their own deprecation cycles, I think it's okay to assume that it's correct. The chance of there being an XP-like backlash against Vista's end-of-life is very low.

I close this issue as a duplicate of bpo-32592 which has a longer history.
