Vista Home Pemium w/updates WM 11.0.6001.7000

When I click a .wmv file, or right click and hit play, the audio
portion begins to play. The player does not open on the desktop. I
have to manually open the player. When I open WM, the video is playing
along with the audio. I have an administrator account.
This is a new computer that originally opened the player when a wmv
file was clicked. I cannot think of any changes I made that would
correspond with this beginning to happen. Originally clicking a file
opened the player.
