The New Beta Experience: This is really cool!!!
The Beta Experience is the new testing platform with tailor-made information for Microsoft developers. By registering to the Beta Experience you will be provided with the opportunity to download or order the latest Beta versions of Microsoft software for testing and the Beta Experience newsletter (6-weekly, terminated with the launch of the final version of the software) as an exclusive source of information.
Great way to get started on Windows Vista and Office 2007!
