I installed 
Windows 7 Enterprise Product Key on my current 
Windows 7 computer, but it turns out I'll be getting a new 
Office Professional 2007 Key next month. The 
Microsoft Office 2007 Product Key guy said that I have to option to uninstall 
Office 2010 Professional Plus Key and deactivate the key so i can install that same 
Office 2010 Standard Key on a different computer. How do I uninstall Microsoft Office 2010 and deactivate the key?
