By default on Windows 7 IPv6 is preferred over IPv4, this is a nuisance when your IPv6 connectivity is supplied via a 6 to 4 tunnel. This tutorial will show you how to set preference for IPv4

1. Open regedit Start -> Search -> regedit
2. Navigate to the following registry key:
   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\tcpip6\Parameters\
3. Create a DWORD value named DisabledComponents, please note this is case-sensitive
4. Edit the DisabledComponents value and set it to 20

   

5. Restart the computer for changes to take effect.

An alternative way off doing this would be to just to import a .reg file containing the following

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters]
"DisabledComponents"=dword:00000020
