When you right click a music folder in Windows Explorer you get this:
To remove the Shop for music online link put this into a registry file and execute it:
Windows Registry Editor Version 5.00 [-HKEY_CLASSES_ROOT\SystemFileAssociations\Directory.Audio\shellex\ContextMenuHandlers\WMPShopMusic]
Great one!
I found this one so irritating but couldnt find it that quick in the registry.
Spares me some time. I get rid of that “Shop online” immediately!
