If you are currently into web development (or are considering of exploring it) using Microsoft's web platform, here's a nice application that will install IIS, the .NET framework, SQL Server, Visual Web Developer Express, and web applications such as BlogEngine.NET and Wordpress the hassle-free way. It is called the Microsoft Web Platform Installer (Web PI). Quoting from Microsoft's website ,"Web PI handles the heavy-lifting by installing and configuring each component of the platform from top to bottom."
I personally used it to install BlogEngine.NET after doing a clean install of Windows 7. To my delight, it worked out of the box without me having to configure anything.
Attached below are some screenshots of the Web PI.
