In the area under "Tools > Internet options > Programs tab > "associate a file type or protocol with a program" > mp3
mp3 is the ONLY audio file type that has *two* instances of WMP. All other common audio formats only show the single instance of WMP (and it works btw).
How could the .mp3 file assocation end up with two WMP entries? Only one plays mp3s. The other does nothing. How do I remove the orphaned WMP instance?
