I had just recently bought a new laptop which has windows 8 installed. I am transistioning from a laptop which had Windows Vista installed with a subscription, I bought this year, which reserved for Windows 7/XP/XP Pro/Vista. When tried to buy a new Product key, from that same subscription, the cart still had Windows 7/XP/XP Pro/Vista but not Windows 8. Would I have to buy a new Norton Internet Security subscription for Windows 8? Would the Windows 7/XP/XP Pro/Vista subscription work on the Norton Internet Security install on Windows 8.
