Pip on Windows should act like a normal Windows program.  If I install 
Python for all users, I expect pipped packages to be installed for all 
users too, unless I specify otherwise.  If installation (for all users) 
requires admin privileges, I expect a UAC box to pop up and ask for the 
admin password.  This is pretty routine, at least with Win7.  Most every 
program I install does this either on installation or on first running. 
  Some Windows operations also pop up a box.  There are only a few 
things that require that I actually login as an admin user.
