Well I am a lil confused by what you are asking BUT. Your old key number for basic will not work on the 7 Premium. Most of the time with crack there are activation programs called loaders.
If you have the loader all you have to do is click on it then click activate and then it will ask for a reboot. With Most of the cracked version that use a loader there is a Windows update that is going to show the OS and not being genuine and some features of Windows will be deactivated. Now if they did give you a new key then all you have to do is enter that number.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
