Share songs, pictures and video to windows media player via DLNA from HTC Desire Z and Desire HD

By
Both the HTC Desire HD and Desire Z models feature DLNA certification, meaning that it is possible to share media files (pictures, videos, music) wirelessly to any other DLNA-compliant device connected to the same network.
Windows Media Player 11 is also DLNA-capable, meaning that media files can be shared between your Android device and your PC at the touch of a button.
