I installed 
windows 7 x64 on my current 
windows 7 x86 computer, but it turns out I'll be getting a new 
Office Professional 2007 next month. The 
Microsoft Office 2007 guy said that I have to option to uninstall 
Microsoft Office 2010 and deactivate the key so i can install that same 
Office 2010 Activation on a different computer. How do I uninstall Microsoft Office 2010 and deactivate the key?
