VLC Windows Installer associates with MIDI files by default
With the default installation settings, VLC is associated with .mid files as the default playback application. When a user then opens a mid file, they are confronted with this message:
"VLC could not decode the format "MIDI" (MIDI Audio)".
According to the Wiki, MIDI support has been dropped completely (where before extra installation steps where necessary), therefore I don't see any sense in keeping this association.
