Nero player icons

Recently installed nero cd burning and player software (I
have windows xp home. As I already have windows media and
real player decided to uninstall the nero media player
using windows uninstaller.. However the icoms for nero
(green "play" triangle) have remained on my tracks saved
under my music rather than reverting to the windows media
player icons. Any ideas how i get them to revert to the
windows icon?

Thanks David
