1. In the Local Area Connection Properties window, untick Internet Protocol Version 6 (TCP/IPv6) and click OK.<br />Note: This method disables IPv6 on your LAN interfaces and connections, but does not disable IPv6 on tunnel interfaces or the IPv6 loopback interface. You need to make change in Windows registry in order to disable the IPv6 on tunnel interface. You can stop here if don&rsquo;t feel like working with Windows registry. If not, proceed with Step 5.<br />

- Double-click !DisabledComponents, set the value as 0xffffffff (hexadecimal value) (just type ffffffff) to disable IPv6 on LAN interfaces, connections, and tunnel interfaces except the IPv6 loopback interface, finally click OK.<br />

- Reboot

Run the following commands:

netsh int ipv6 isatap set state disabled
netsh int ipv6 6to4 set state state''disabled

Change the following registry keys by downloading and importing the .reg files:<br /> DisableIPHelperService.reg: !DisableIPHelperService.reg<br /> DisableIPv6TunnelAdapters.reg: !DisableIPv6TunnelAdapters.reg

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\iphlpsvc]
"Start"''dword:00000004

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\TCPIP6\Parameters]
"DisabledComponents"''dword:ffffffff

Reboot for the changes to take effect.
