Does changing Windows XP for Windows 7 affect the information fund on my computer?
 

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