I also purchased this $17 dollar Windows Media Center remote control. It requires no software, and works with Windows XP, Vista and Windows Seven versions of Windows Media Center. It also gives a remote-controlled mouse complete with left and right-clicking capability. It comes with the remote control, an infrared USB dongle, and two “AAA” batteries to power the remote. This remote really makes Windows Media Center usable, particularly if you have the computer attached to a large flat panel LCD HDTV.
