`py` is not installed by default *and* trying to run it results in a popup asking if you want to install it. `python3` is installed by default. This hopefully should not be too disruptive to people on Windows, since they should be going through `x.ps1` instead anyway. Just in case, I've added a check for Cygwin and Msys (i'm not sure how else you'd get a bash shell on windows).
