Winows Media Center is an application designed to serve as a home-entertainment hub. It is included in Windows XP Media Center Edition and premium editions of Windows Vista (Vista Home Premium and Vista Ultimate). It is designed to be controlled by special remote controls which prominently feature the Green Button (similar to the logo to the right), but can also be operated with a mouse and/or keyboard. This button is used to either launch Media Center from Windows or to return to the Start Menu from within the application. Media Center visualizes the computer user's pictures, videos, and music from local hard drives, optical drives, and network locations. It then categorizes them by name, date, tags, and other file attributes. Media managed through Media Center can also be relayed via a home network to standard TV sets via the specially designed Windows Media Center Extender or the Xbox 360.
