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?
