Here's the problem:
I installed RealONE Player (a very useful, but dangerous thing!) and all my media extensions where authomatically associated to it. I tried with the advanced config to force it to relase the files (I'm still in love with Microsoft's Media Player 7.01) but it didn't work. So I uninstalled the Realplayer and removed all the registry and shell entries it left behind (or at least I hope so) with jv16 Power tools' app.
All my media files are now back to Media Player, but their icons do not appear anymore. When I double-click on them, they open normally, but I am not able to force their icons back.
I noticed a few of them actually where restored, but the most common ones are still missing (.MP3,.M3U,.MPGA,.MPG,.MPEG,.MPV,.MPS,.M2V,.M1V,.MPE,.MP2,
.MPA,.WAV,.AU,.AIFF,.AIF,.AVI,.MID,.MIDI,.RMI,.WMA,.CDA).
I tried a lot of times deassociating, reassociating and changing icons in the Folder Options, but it doesn't work!
How may I restore the missing icons back?
