Want a free copy of Vista Business Edition and Office 2007 Professional?

Microsoft is giving away a limited number of full licenses for high-end versions of its flagship products to people who watch six Webcasts -- three for each product -- with titles like "Introduction to Windows Workflow Foundation". At list prices, these two products would cost nearly $800. The Webcasts appear to be geared toward software developers and other IT professionals.

The promotion is going by the name "Power Together."

Of course, there are several caveats: must be over 18 and a legal U.S. resident, and not employed by a Microsoft Partner or the Microsoft Developer Network. The offer expires Feb. 28.
