bash on Windows...
is actually kinda useless at the moment. The problem is that as soon as you start bash on Windows, you're in a totally different environment. You even have to create a separate user for it, making it a completely disconnected experience.
You can't do a lot of things either. Windows tools to manage the OS like ipconfig don't exist there... and neither do their Linux counterparts. I'm not entirely sure what it's meant to be for.
