OK. I'm not sure I care enough to remind you, but if you want to
follow up at that point, then that's great. Can you start by proving
your assertion that pip is trying to install Visual Studio?

I can't accept that - because there's no code that's run by "python -m
pip install -U pip" that would try to install Visual Studio. If
nothing else, how would it know where to download it from? If that's
not the command you used to upgrade pip, then can you remind me (if
you've already said) or say what command you *did* use? If you can't
tell me what that command was, then can you accept my word that
"python -m pip install -U pip" cannot have been the cause of an
attempt to install Visual Studio 2015?

Well, the above for a start. But also, that it's worth my while caring
about this. I take it quite personally that you keep insisting that
pip can or would attempt to install Visual Studio, without backing up
that assertion. As far as I can tell, you think that i shouldn't.

Anyway, this is getting nowhere, so I won't comment further.
