2. In the User Account Control dialog box, click Continue.
3. In Registry Editor, locate and then click the following registry subkey:
4. Double-click DisabledComponents to modify the DisabledComponents entry.

Note If the DisabledComponents entry is unavailable, you must create it. To do this, follow these steps:
1. In the Edit menu, point to New, and then click DWORD (32-bit) Value.
2. Type DisabledComponents, and then press ENTER.
3. Double-click DisabledComponents.
5. Type any one of the following values to configure the IPv6 protocol, and then click OK:
1. Type 0 to enable all IPv6 components.

Note The value "0" is the default setting.
2. Type 0xffffffff to disable all IPv6 components, except the IPv6 loopback interface. This value also configures Windows Vista to use Internet Protocol version 4 (IPv4) instead of IPv6 in prefix policies.
