Apparently Vista. I just used netsh for the first time today.

netsh interface ipv4 show subinterfaces
netsh interface ipv4 set subinterface "1" MTU=576 stored=persistent

(or something like that)
I guess that's better than hacking the windows registry to change MTU
size. But still a bit cryptic and relatively undocumented. I had to
google from linux to get that gem. Because I couldn't get anything across
the internet aside from a ping until I made the change. Which is odd
because it worked fine six months ago when I last booted windows.
