Teredo Tunneling Pseudo-Interface?

Since installing Vista Hotfix KB299451 I have a new network adapter listed
in device manager: Teredo Tunneling Pseudo-Interface - with an exclamation
mark: "The device cannot start (Code 10)".

I am aware that this network adapter is required to enable IPv6
functionality over IPv4 but am not sure why it did not show up before
installing this hotfix nor do I know how to correct this error.

I probably don't need IP6 functionality, though.
