So I was told by a friend that you can burn windows 7 to a disc and then reuse a windows 7 code. Let me elaborate, I have a laptop with pre-installed windows 7 on it, anyway, my friend says that you can re-download windows and then burn it onto a disc, put it into a new c and use the same serial code. Can you do this and please tell me how! Would save me £60 on a new pc build!
