title: Install virtualenv on windows without pip
body: <p>In linux, you have the option to install virtualenv from apt-get so you don't have to install pip globally. This helps because you can't install a pip package globally for mistake. In the official documentation, they don't explain how to do that in windows. I found the command: <em>"python install setup.py"</em> but even with that I don't know where the virtualenv command is generated. </p>
