So after a bit of a problem I can finally reinstall windows 8 but when it asks me for my product key I have no idea where it is because windows 8 came with my PC which is brand new so it isn't on a box or anything. Can someone please help me find it?

There will be a sticker on either the laptop or the power supply brick with the information you need.
