Vista hidden tunnel

I have 4 hidden tunnel adapters when I do ipconfig /all.

I read a post that said these are part of the ipv6 stack.

I'm on a 64 bit version of Vista and read a post where others have only 2, but I'm unsure whether they have 32 or 64 bit os.


2 of each are very similar in their description and would only have to verify whether the other 2 came from a recend openvpn install I did.

 

here is how the descrition lUUks
