how to remove tunnel adapters which i dont want.

I am having Windows Vista on my computer and having some issues with it. I recently create some VPN connections and then I was unable to connect to my pc in office and so I deleted all the VPN connections. But when I did an ipconfig/ all then I checked that there was some Tunnel adapters that werein the disconnected state, so is that correct or do I need to erase it somehow? Below are the results of ipconfig/ all:

There is full IPv6 stack which is enabled by default in Windows Vista and these extra interfaces are part of that. So, there is no issues whether you want to remove them or not.

Even I am facing the same issue on my computer. Can anyone tell me how to remove the list of unused tunnel adapters in ipconfig because it seems some sort of bugs to me.

You might have to modify the registry and to enable or to disable IPv6 or to selectively enable or disable components of IPv6 automatically, click the Fix this problem link. Then, click Run in the File Download dialog box, and follow the steps in this wizard, given at this link - http://support.microsoft.com/kb/929852
