how do i restore a setting?

I have a problem playing certain .avi files in media player, this has nothing
to do with codecs because i've played some of the files in it before. Usually
there is a box that asks whether or not i want to play the file and a check
box is present that says always do the following and i clicked no by mistake,
now it will not play the files. Is there a way for me to restore the default
settings of media player? i removed and reinstalled media player but the
settings are still saved.

The settings should be under
HKEY_CURRENT_USER\Software\Microsoft\MediaPlayer
, most likely, but possibley
HKEY_LOCAL_MACHINE\Software\Microsoft\MediaPlayer
, presumably identified with the string ".avi"... ?
