Well, finding the wireless key on a Windows laptop can be 
interesting. I am guessing you would have to dig into the registry 
to find it. I know it is hidden when you look at the wireless 
settings. (Like when you enter a password.) I have not dug into the 
registry to see if it is encoded there.

Now, if the administrator did things right, there should be a 
network setup USB key or disk with all the network settings needed 
to connect to the wireless network. It is set up so that all you 
need to do is put it in and auto-run it - it sets things up without 
the user having to know the details or the key. It makes setting up 
a new computer to connect to the wireless network a snap.
