As part of the ISV training series, you can take advantage of MSDN Virtual Labs. This series of hands-on labs are hosted by Microsoft—so there's no need to format hard drives or dedicate computers, and nothing to install. With 35, no-cost lab modules to choose from, you're sure to find the training you need. Each module includes a downloadable instruction manual and a 90-minute block of time in which to complete the module.
Check out Microsoft SQL Server 2005, the 2007 Microsoft Office system, Windows Vista, Visual Studio 2005, and Visual Basic/.Net any time you want, without the hassle of setting up your own testing environment.
