Dashboard
See also: Xbox 360 System Software
The Xbox 360's original graphical user interface was the Xbox 360 Dashboard; a tabbed interface that featured five "Blades" (formerly four blades), and was designed by AKQA. It could be launched automatically when the console booted without a disc in it, or when the disc tray was ejected, but the user had the option to select what the console does if a game is in the tray on start up, or if inserted when already on. A simplified version of it was also accessible at any time via the Xbox Guide button on the gamepad. This simplified version showed the user's gamercard, Xbox Live messages and friends list. It also allowed for personal and music settings, in addition to voice or video chats, or returning to the Xbox Dashboard from the game.

On November 19, 2008, the Xbox 360's dashboard was changed from the "Blade" interface, to a dashboard reminiscent of that present on the Zune and Windows Media Center, known as the "New Xbox Experience" or NXE.

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 capabilities, adding compatibility for new accessories, and fixing bugs in the software. The latest Dashboard update was made available on November 17, 2009.

New Xbox Experience
Further information: Xbox Live, section "New Xbox Experience"
At E3 2008, at Microsoft's Show, Microsoft's Aaron Greenberg and Marc Whitten announced the new Xbox 360 interface called the "New Xbox Experience" (NXE). The update was intended to ease console menu navigation. Its GUI uses the Twist UI, previously used in Windows Media Center and the Zune. Its new Xbox Guide retains all Dashboard functionality (including the Marketplace browser and disk ejection) and the original "Blade" interface.

The NXE also provides many new features. Users can now install games from disc to the hard drive to play them with reduced load time and less disc drive noise, but each game's disc must remain in the system in order to run. A new, built-in Community system allows the creation of digitized Avatars that can be used for multiple activities, such as sharing photos or playing Arcade games like 1 vs. 100. The update was released on November 19, 2008.[57]

While previous system updates have been stored on internal memory, the NXE was the first to require a storage device—at least a 128 MB memory card or a hard drive.

Multimedia
The Xbox 360 supports videos in Windows Media Video (WMV) format (including high-definition and PlaysForSure videos), as well as H.264 and MPEG-4 media. The December 2007 dashboard update added support for the playback of MPEG-4 ASP format videos.[58] The console can also display pictures and perform slideshows of photo collections with various transition effects, and supports audio playback, with music player controls accessible through the Xbox 360 Guide button. Users may play back their own music while playing games or using the dashboard, and can play music with an interactive visual synthesizer.

Music, photos and videos can be played from standard USB mass storage devices, Xbox 360 proprietary storage devices (such as memory cards or Xbox 360 hard drives), and servers or computers with Windows Media Center or Windows XP with Service Pack 2 or higher within the local-area network in streaming mode.[59][60] As the Xbox 360 uses a modified version of the UPnP AV protocol,[61] some alternative UPnP servers such as uShare (part of the GeeXboX project) and MythTV can also stream media to the Xbox 360, allowing for similar functionality from non-Windows servers. This is possible with video files up to HD-resolution and with several codecs (MPEG-2, MPEG-4, WMV) and container formats (WMV, MOV, TS).[62]

In the UK the Xbox 360 will be enabled to download and display BT Vision video content.[63] Since 27 October 2009 [64] , UK and Ireland users will also be able to access live and on-demand streams of Sky television programming.[65][66][67][68][69][70][71][72]

XNA community
Main article: Microsoft XNA
XNA Community is a feature whereby Xbox 360 owners can receive community-created games, made with Microsoft XNA Game Studio, from the XNA Creators Club . The games are written, published, and distributed through a community managed portal. XNA Community provides a channel for digital videogame delivery over Xbox Live that can be free of royalties, publishers and licenses.[73][74] XNA game sales, however, did not meet original expectations.[75]
