Will the Windows 7 Ultimate upgrade work for computers with Mac software?
 

I installed Microsoft Office 2007 Product Key on my current computer, but it turns out I'll be getting a new one next month. The Microsoft guy said that I have to option to Microsoft Office 2007 Pro Windows 7 and deactivate Microsoft Office Standard 2007 Serial key so i can install that same Microsoft Office Professional 2007 Serial Key on a different computer. How do I uninstall Office Professional Plus 2007 Activation and deactivate the key?

How do I change back from Windows 7 to Windows Vista?
 

Ok, so I upgraded Office Standard 2007 Serial Key Windows Vista Home Premium to Office 2007 Professional Plus Serial Key and I was wondering whether I could Office Pro 2007 Activation Key from Windows 7 to Windows Vista? Windows 7 makes the Microsoft Office Ultimate 2007 Serial Key horribly blur, is not Microsoft Office Professional Plus 2007 Serial with tons of programs and I am not used to it. I can't play my game and I really want to change back as soon as possible. Can anyone help me? Also, I can reinstall everything if needed, but I don't know how to. Please help!
