At first I thought a friend's machine (win 7) had associated .exe with windows media player (all icons on the desktop had windows media center icon, and clicking on anything would start windows media player).
But it seems that .lnk's are associated to media player?!
I compared the registry for hkey_classes_root for .exe and .lnk with a machine working OK and they look the same.
anywhere else to look? Tool to fix this?
