If you do not use network sharing and you are not connecting to other computers on LAN:
Uninstall all network protocols from your adapter, keep only IPv4, you can un-check IPv6.
You can also disable LMHOSTS and NetBIOS. Setup
custom DNS servers, if you wish.
Note, that NetBIOS might be required, if you are using ADSL connection/modem.
Disabling IPv6 is optional, but IPv6 causes more trouble than it is worth.
Code:
netsh int ipv6 isatap set state disabled
netsh int teredo set state disabled
netsh interface ipv6 6to4 set state state=disabled undoonstop=disabled
reg add "HKLM\System\CurrentControlSet\Services\Tcpip6\Parameters" /v "DisabledComponents" /t REG_DWORD /d "255" /f
