Today at the Microsoft Developer Conference in Los Angeles Microsoft demoed the latest build of Windows 7. Different from the PDC Windows 7 build that will be given to attendees, a post Milestone 3 build was shown in the keynote that was more feature complete. In fact, the build demoed at the keynote was about 130 builds past the Milestone 3 build.
