It’s great to see Windows 7 Beta finally released to the world! We're very proud of what has been accomplished over the last months; in many ways, it sets a new quality bar for a beta operating system release. Building on top of the Windows Vista foundation, Windows 7 adds a great deal of polish and refinement to both the user interface and the underlying architecture, while at the same time introducing many new features and improvements that support new hardware, give power users and casual users alike better tools to manage their digital lives, and enable new classes of application experience.
