To disable IPv6 on all interfaces, configure the following registry value:

Registry Hive: HKEY_LOCAL_MACHINE
Registry Path: \SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\

Value Name: DisabledComponents

Type: REG_DWORD
Value: 0xff or 0xffffffff

Microsoft updated article 929852 with regard to disabling all IPv6 components, changing the value to 0xff. A value of 0xffffffff results in a 5-second delay in system startup. However, either value can be used to disable all IPv6 components.
