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