lowlander : Please clearly advise the detailed steps of performing "Right click on MP3 in Windows Explorer > Properties and change the default program to M" as being little confused. Do I have to run a MP3 file to have that done?
Thanks for the procedures provided!

Right click on MP3 in Windows Explorer > Properties and change the default program to MM.

lowlander: I did that too as well as chcek on MP3(mp3) on select extensions to be associated with MediaMonkey under Audio Topic and still all my mp3 are remained with Windows Media Player logo sign. Please advise what I should do now and thanks for the help.

Also enable re-associate on startup and restart MediaMonkey.

lowlander: thanks for the advice. When I click okay at OS integration, all my mp3 files in folders and files in Drive C/D are still in Windows Media Player logo sign. Do I have to remove and re-install mediamonkey again to get this done? Thanks!

Tools > Options > OS Integration

Originally all my mp3 files are in Mediamonkey logo sign. Weeks before, I discovered they were all in RealPlayer logo sign and when I removee RealPlayer, they changed to Windows Media Player logo sign.
Please advise how I can have all my mp3 files back into mediamonkey logo sign and thanks for the assistance!
