I disabled two context menu items from VLC, but they are still there, even after having turned my computer off and back on again.
the two appear context-menu entries for me only when I select a multimedia file, otherwise the 2 Entries not available
otherwise you look here in your registry
HKEY_CLASSES_ROOT\Directory\shell\AddToPlaylistVLC
