The Windows build refers to a Python DLL and will load it if it can find
it. However, Python itself is not included with Windows Vim and must be
separately installed. It must also be the same version of Python (e.g.,
python26.dll) and the DLL must be in the search path, :h python-dynamic

The average Vim user on Windows is, I suppose, somewhat likely to already
have Python, and, if not, will likely be amenable to installing it
-- especially if it gets them some useful Vim extensions.
But this is all supposition; I know of no way to get meaningful numbers on this.
