The installer's option to add Python to PATH adds both the
installation directory and the scripts directory. The latter has
"pip.exe", assuming pip was installed.

> py -m pip install foo

If the `pip` command is on PATH, for an installation or active virtual
environment, it's usually fine to use it instead of `py -m pip` or
`python -m pip`. But there's one caveat. The `pip` command can't be
used to upgrade pip itself. For that you have to run the module via
`'py -m pip` or `python -m pip`.
