This is all thanks to that wonderful benevolent cartel known as the MPAA. Realising that kids are becoming less and less likely to obey their edicts, the MPAA have released a ‘utility’ that allows parents to delete music files from their child’s computer (incidentally this would probably be illegal in the UK as it modifies computer data without the owner’s permission). The catch is that the ‘scan for copyright’ program seems to, well, not scan for copyrighted music. It deletes Windows components.
