[SOLVED] upgrade

is it necessary and can i use the same product key to activate Windows

If you dont there are a few possible outcomes. It might bootup ok and work but more likely if it boots you will be chasing issues indefinitely or it might not even boot. It is recommended to just reinstall.

As for licence key, what version of Windows and where did it come from? Did your licence come from a prebuilt system or did you buy it?
