I am using secondary user account Office 2010 Professional Plus and I am considering getting Windows 7. I have been shopping online and I have found Office Standard 2010 Activation and Windows 7 Upgrade. When I think of an upgrade, I think of it as something to improve Office 2010 Activation Key I already have. Is this the case with Windows 7 Ultimate Product Key? Is it an improvement on Windows 7? If so, why hasn't the upgrade been integrated with the Windows 7 software?
