nce 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. Such updates are mandatory for users wishing to use Xbox Live, as access to Xbox Live is disabled until the update is performed.[citation needed] New Xbox Experience Further information: Xbox 360 system software § User interface 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 (although the color scheme has been changed to match that of the NXE Dashboard). 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. While previous system updates have been stored on internal memory, the NXE update was the first to require a storage device—at least a 128 MB memory card or a hard drive. Microsoft released a further update to the Xbox 360 Dashboard starting on December 6, 2011. It included a completely new user interface which utilizes Microsoft's Metro design language and added new features such as cloud storage for game saves and profiles, live television, Bing voice search, access to YouTube video
