Dashboard

The Xbox 360's original graphical user interface is the Xbox 360 Dashboard; a tabbed interface that features five "Blades" (formerly four blades), and was designed by AKQA. It can be launched automatically when the console boots up without a disc, or when the disc tray is ejected. However, the user may choose to launch a game automatically if a disc is inserted. A simplified version of it can also be accessed at any time via the Xbox Guide button on the gamepad. This simplified version shows the user's gamercard, Xbox Live messages and friends list. It also allows for personal and music settings, in addition to voice or video chats, or returning to the primary Dashboard from the game.
As of November 19, 2008, the Xbox 360's dashboard has changed from the "Blade" interface, to a dashboard reminiscent of that present on the Zune and Windows Media Center.
Since the console's release, Microsoft has released several updates for the Dashboard software. These updates have included adding new features to the console, enhancing Xbox Live functionality and multimedia playback cabilities, adding compatibility for new accessories, and fixing bugs in the software. The latest Dashboard update, revision 2.0.7357.0, was made available on November 19, 2008.
