Problem with Media player / Guild wars

Hi, i have windows 7 and lately everytime i close guild wars screen the windows media center screen pops up each time its getting annoying , im thinking it must be some small setting that needs to be turned of in media or maybe guild wars idk I tried going to manage library options and there i saw a list of game and such , so i unticked them guild wars being one of them and clicked save, but its still popping the media center screen up after guild wars is closed, i don't know where else to look to turn anything off ???

Right click on the icon you use to run Guild Wars, go to Properties, go to the Shortcut tab, and check to see if the "Target:" field ends with -mce. It should look something like this Target: "C:\Program Files (x86)\Guild Wars\Gw.exe" -mce. If it does just delete the -mce part because that's the thing that's starting Windows Media Center.

WTG enigma that was it yay
