I built a new PC and installed Windows 7 Ultimate Trial and all the necessary apps (Firefox, MSE, Skype etc..)
I then purchased a serial and tried to activate it. I got an error message saying the serial is for a different version of Windows 7 and got clarification that the serial number is for Windows 7 Ultimate N.
Does anyone know how to change my installed edition of Windows 7 Ultimate to Windows 7 Ultimate N, the difference between the two editions are so small (according to Wikipedia) that I would hate to have to start all over again.
