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