I am using Windows XP and I am considering getting
Windows 7 Home Premium 64bit. I have been
Windows 7 Activation online and I have found Windows 7 and
Windows 7 Professional Serial Key. When I think of an upgrade, I think of it as something to improve something that I already have. Is this the case with
Windows 7 Home Premium Activation Key? Is it an improvement on Windows 7? If so, why hasn't the upgrade been integrated with the
Windows 7 Pro?
