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