cant delete play from context

Im trying to delete play from right click context from audio cd and drive but i wont delete..When i right click on a audio cd or a dvd movie there is a option called paly and when i click on it, it starts playing with real player and i rather have it play with windows media player when i click on play or better yet would just like to delete it if its possible..

I went to hkey_classes_root on regedit and then on audioCD and found the entry play and when i deleted it, the play option was still there on right click.

please help.

i have included a screenshot and marked it with a green line

Thanks , i was able to remove it thru the registry by going to hkey classes root dvd and audioCD folder.

I already had windows media player as my default for audiocd but everytime i clicked play it would start with real player which is very strange.

I usually prefer just to have autoplay on my context as that way i get to choose which program i want to use.
