I have a laptop i am currently running a non activated version of windows 8 (i have a desktop thats already using that copy) but the laptop i have has a sticker on the underside with a windows 7 home premium key code on it. If i get any copy of windows 7 home premium can I use this key code to activate it or is the key code tied to a specific windows disk?

okay, so my friend has a windows 7 home premium disk, can i use that to install it with my keycode? so the keycode is only tied to the laptop and not a specific windows disk?
