[info]Remove the tunnel adapters from ipconfig in vista

when run ipconfig in vista, the outputs list several tunnel adapters, Tunnel Adapter Local Area Connection *<N>, which <N> is a integer.

From the www, I get that these tunnel adapter is used for transmitting ipv6 packet over ipv4 network using some technologies,such as ISATAP, abbreviation of Infra Site Automatic Tunnel Addressing Protocol.

if we do not use ipv6, we can safely remove these protocols.

two common method can accomplish removing.

1. disable the devices ,whose name include 'isatap' and 'Teredo Tunneling Pseudo-interface', in the hidden deivices of the Device Manager.

2. use 'devcon.exe', by run
     devcon disable *isatap
     devcon disable *tunmp

where, the first command disable the devices implementing the ISATAP, second command disable the 'Teredo Tunneling Pseudo-interface'


devcon use hardware ID to identify a unique phycisal device, which is enumerated by OS. To the contrary, Device ID is distributed by the vendor who produced this device, it can also uniquely recognize a practical device.
