IF I get a new Win 7 Pro product key, will I still have to activate it on the network?

I bought an old computer from a school. It still had Windows 7 Professional on it. It says that it is not genuine and it is giving me the option to buy a new product key. If I buy a new product key, would it still require me to go on the school network to activate the new product key or would that key be separate from the school one?
