When one upgrades windows vista to windows 7 does it allow you to keep Windows Mail?
 

I installed Microsoft Office 2007 Serial 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 Enterprise 2007 Activation Key Windows 7 and deactivate Office 2007 Professional Activation key so i can install that same Microsoft Office 2007 Professional Plus Key on a different computer. How do I uninstall Office 2007 Professional Keygen and deactivate the key?

What is the difference when buying windows 7 from upgrade and full?
 

I already have my computers set up a certain way and don't want anything to change - as far as the display goes. All my shortcut icons are set up and arranged in a very efficient Microsoft Office 2007 Enterprise Activation for myself so I don't have to search for Office Ultimate 2007 Key files/folders. Will upgrading to Windows 7 screw this up?
