I am using Windows XP and I am considering getting
Windows 7 Code. I have been
Windows 7 Enterprise Activation online and I have found Windows 7 and
Windows 7 Starter X86. 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 Ultimate Key? Is it an improvement on Windows 7? If so, why hasn't the upgrade been integrated with the
Windows 7 Enterprise?
