Disable Bluetooth File Transfer - Windows 7

How do I disable Bluetooth file transfer for Windows 7? I am planning to see if it can be done via Group Policy (custom adm or GPP) or by creating a power shell script.

I read the existing questions here but its getting me nowhere. http://social.technet.microsoft.com/Forums/office/en-US/0a04b41b-05a8-4d7b-9ae0-212137cc4af7/restrict-bluetooth-file-transfer?forum=winserverGP

Thanks in advance.
