I am using configuration Office 2010 Standard Activation Key and I am considering getting Windows 7. I have been shopping online and I have found Office 2010 Pro Plus Key and Windows 7 Upgrade. When I think of an upgrade, I think of it as something to improve Office Standard 2010 X86 I already have. Is this the case with Windows 7 Home Basic X86? Is it an improvement on Windows 7? If so, why hasn't the upgrade been integrated with the Windows 7 software?
