Specifies whether individual applications can alter the type of service (TOS) bits in the header of outgoing IP packets. In general, individual applications should not be allowed to manipulate TOS bits, because this can defeat system policy mechanisms.
You must restart the computer for changes to this entry to take effect.

The last bit is currently unused. For more information about the TOS byte, see IETF RFC 1349: Type of Service in the Internet Protocol Suite.
