Disable ipv6 protocol in Windows 7/Vista

1. In Registry Editor, locate and then click the following registry subkey:
   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\
2. Double-click DisabledComponents to modify the DisabledComponents entry.
   
   Note If the DisabledComponents entry is unavailable, you must create it. To do this, follow these steps:
   In the Edit menu, point to New, and then click DWORD (32-bit) Value.
   Type DisabledComponents, and then press ENTER.
   Double-click DisabledComponents.
   
3. Type 0xffffffff to disable all IPv6 components, except the IPv6 loopback interface. This value also configures Windows Vista to use Internet Protocol version 4 (IPv4) instead of IPv6 in prefix policies.

That's it!
