Microsoft just announced the Web Application Installer. It is an installer designed to help get users of the Windows operating system up and running with some popular web applications. Guess what? It comes with support for Drupal. I don't know enough about their roadmap but this could introduce Drupal to thousands of new users. Oh my!
From the Web Application Installer page:
Web Application Installer provides support for popular ASP.Net and PHP Web applications including Graffiti, DotNetNuke, WordPress, Drupal, OSCommerce and more. With just a few simple clicks, Web Application Installer will check your machine for the necessary pre-requisites, download these applications from their source location in the community, walk you through basic configuration items and then install them on your computer.
I don't have a Windows machine so I can't test it out, but it sounds like a great way for Windows users to explore Drupal. (Hat tip: Jelle Druyts)
