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