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