When I did an ipconfig, I noticed there were some weird bits of information called "Tunnel adapter isatap" and "Tunnel Adapter Teredo Tunneling Psuedo-Interface"

I hear that this is used for compatibility and has to do with NAT, or something. But I also hear it can have potential security risks. Should I disable this? What programs would use it for compatibility and would I lose internet capability with certain programs or games?

I also heard somewhere than you can type a CMD command to "refresh" or "reset" these. When I did that, I got the message that "an error occured while releasing" them, due to the files not being located. Not sure why?

Thanks for your help

Tunneling is how you do secure (encrypted) communications across an
untrusted network (the Internet).

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

It is used with IPv6.
If your IP address has four group of numbers like x.x.x.x then you have IPv4 IP address (eg. 192.168.1.10).
We are talking about internal IP address the one your router uses.

If you are not using IPv6, then you can disable Teredo, ISATAP and IPv6 all. Make sure any of your devices are not using IPv6.
If you are using the IPv6, then you may need it. Teredo Tunneling is used to connect to IPv4 devices in the compatibility mode while you are using IPv6 yourself.

Anyway, if you get problems by disabling tunneling then you can come here again at BC :)

This is how you can disable Teredo tunneling.

You can also do the same for ISATAP just replace teredo in the command line with isatap like this :
netsh interface isatap set state disabled

If it ain't broke, don't fix it.

Thanks for your replies, but my main question was, would I lose any capability by disabling it? Would there be any online services or games that would be affected by disabling this?

Yes you would lose some capabilities that IPv6 provides.Yes some online services and games might get affected. But then again, they might not.
If you are confused, do not disable it. As dc3 said, if it ain't broke, don't fix it.

I suppose, but I read on wikipedia that it has potential security issues?

As I have said before, you can disable IPv6 and check if disables any of functionality. If not then ok, if something does not work then enable it again.

Yes there is security concern, but you will have to authorize an application before it can use Teredo. You can do some research on that application before authorizing or ask on BleepingComputer.
