  1. You can change de registry value and use regedit: Ordinateur\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters
    The key DisabledComponents must be at 0 (Key =0 for IPV6 and IPV4).
    On my computer I had to disable the startup of FastestVPN Service in msconfig. This program systematically reset the registry key to the value FF (Key=FF IPV4 only).

  2. I need to know how to stop somebody from changing my ipv6 to no internet access. It is happening quie often.
