Disable IPv6 in Vista & Windows 2008

How do I disable IPv6 in Windows Vista and Windows Server 2008?

Add the following registry value (DWORD type) set to 0xFF:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\DisabledComponents

This method disables IPv6 on all your LAN interfaces, connections, and tunnel interfaces but does not disable the IPv6 loopback interface. You must restart the computer for this registry value to take effect.

Natomiast żeby się pozbyć tunelowania TEREDO, to trzeba wyświetlić ukryte urządzenia w Device Manager - View - Hidden Devices -> Disable
