So my friend brought her laptop over for me to look at. She is on a cheap
dial up plan and she is happy with that. I do an ipconfig /all and see 438
438! 6to4 adapters!
So I disable ipv6 with regedit, load up this useful tool,
and spend a while selecting and deleting tons of teredo and 6to4 virtual
NICs she would never need. Lo and behold, her laptop is actually usable!
She says it is so fast now, haha

Ciao, Dave
