Here is what you have to do;

PDC attendees got the Windows 7 pre-beta build, and Microsoft told them that a public beta would be available in early 2009. But you don't want to wait until then, right? You want Beta 1, right now. Well, I can't give you that, but I can tell you how you can get your hands on a physical copy of the Windows 7 Beta 1 DVD. You'll need $100 and a desire to visit one of the upcoming episodes of the MSDN Developer Conference (MDC). Here are the dates and locations you can register for:

* 12/9/08 - Houston, TX
* 12/11/08 - Orlando, FL
* 12/16/08 - Atlanta, GA
* 1/13/09 - Chicago, IL
* 1/13/09 - Minneapolis, MN
* 1/16/09 - Washington, DC
* 1/20/09 - New York, NY
* 1/22/09 - Boston, MA
* 1/22/09 - Detroit, MI
* 1/26/09 - Dallas, TX
* 2/19/09 - San Francisco, CA

All attendees will be getting a copy, though it's not clear whether Microsoft will be mailing them out or giving them in person (rumor has it that the DVDs will only be ready by January 13). Check out the sessions and about pages for more information. If you're going, you might as well check out all the other things Microsoft will be discussing, including Windows Azure and the Azure Services Platform, Live Framework and Mesh services, Microsoft SQL Data Services, Silverlight 2, ASP.NET 4.0, JQuery, Oslo, Visual Studio 2010, and Microsoft F#. Still not enough for you? Well, there will be giveaways at each event as well: three MSDN Subscriptions, three Robotics Packs, three Mobility Packs, and three Gamer Packs.
