Adding installed PIP package to path automatically

For my package, foo, I'm using the following setup.py:

from setuptools import setup

setup(name='foo',
      version='0.0.1',
      description='Lol',
      url='https://github.com/foo/foo',
      author='legend',
      author_email='lol@gmail.com',
      license='GPLv3',
      packages=['foo'],
      install_requires=["bar"],
      entry_points = {'console_scripts': ['foo = foo:main']},
      keywords = ['foo'],
      zip_safe=False)

When testing on my Arch system, it added the script to PATH automatically so I could just run foo on my command line and it'd run the function main() automatically. Then, I booted up a VM and tested it on Windows 7. Pip installed the package just fine, but it wasn't in my path!

Help?
