Hi Rohan,
Did what u had suggested earlier but perhaps I'm missing a simple trick. Once I change the file association the icon of media player classic is correctly displayed but only in the main folder options>file type >change window--the advanced button is modified to restore after this. The icons of mp3 files(in a folder on my desktop) remain those of WMP 10. On double clicking these files the songs,however are played correctly in media player classic.
Oh well, its not such a big deal and you've tried. Thx for your time.
