It's intended behaviour (to my knowledge). Or at least, we don't
intend for people to install two different patch versions in parallel
(at least not with the official installers). I thought this behaviour
was always the case. It may be related to the installer technology
involved, though, so it may have changed when we switched to wix.
You're right it doesn't seem like the details are well documented. It
might be worth raising a docs bug on bugs.python.org asking for the
details to be clarified.

I downloaded the 64-bit Windows MSI for Python 2.7.15 and upon finishing the
installation, I noted that prior Python installs had effectively been removed,
only leaving a Lib and Scripts folder in the directory to which said prior
version had been installed. For what it's worth, it appears this is only true
if I install for 'All users' rather than for 'just this user'.
I believe the installer warns that it overwrites previous releases of
the same x.y version.
I can't find anything in the release notes, docs or on this mailing list that
describes the motivation for doing this. I personally find that having
multiple versions installed on Windows is very helpful for being able to target
distribution version for the purposes of constructing virtualenvs.
Can anyone say whether this is intended behavior?
