I recently discovered that my initial installation of IIS 7.5 on Windows 7 professional didn't include basic features like serving static content... surprise!
So I reinstalled IIS following this guide on iis.net. On point number 7 of that page, it describes how to enable "Common Http Features" that are not enabled by default like: Directory browsing, or Static Content. This is the part I had missed before, I couldn't imagine that the default installation didn't include these basic features.
