I doubt will work during using Office Professional 2010 Key and I am considering getting Windows 7. I have been shopping online and I have found Office 2010 Professional Plus 32bit and Windows 7 Upgrade. When I think of an upgrade, I think of it as something to improve Office Home And Business 2010 Serial I already have. Is this the case with Windows 7 Home Premium X64? Is it an improvement on Windows 7? If so, why hasn't the upgrade been integrated with the Windows 7 software?
