More likely explanation is that Administrators > group have full access to the object in question. They don't. The issue at hand is that Cygwin uses SeBackupPrivilege and SeRestorePrivilege if otherwise the object in question would not be accessible. The moral of the story is to drop those privileges / capabilities when you don't need them via cygdrop or just don't use an administrative account that comes with them in the first place.
