I want to uncheck 'Internet Protocol Version 6 (TCP/IPv6)' from connection properties but I couldn't find a way to do it on Vista+ machines! Setting 'DisabledComponents' to '0xffffffff' in 'HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters' didn't help! Although I couln't find any IPv6 binding (ipconfig /all) after reboot - 'Internet Protocol Version 6 (TCP/IPv6)' is still checked in Local Area Connection Properties! Any help? BR, UEZ
