I currently have a system set up and running Win7 Home Premium OEM; if I upgrade the system to Win7 Pro using the Anytime Upgrade program, can I then turn around and use the original Win7 HP OEM disc and install it on a new system. Since both systems would have a different version of Win7 with different licenses, it seems possible. I have not been able to find a reference to this question online so I'm hoping someone can give me a definitive answer
