I just want to know how
Windows 7 Home Premium can I format my laptop
Windows 7 Ultimate, so that the only
Microsoft Office 2007 Key thing remaining is the
Office 2007 Pro Key itself, as if I have just bought
Office Pro Plus 2010 Key. I don't have any Microsoft Office 2010 installation CD's, because
Microsoft Office Pro Plus came with the laptop, so how can I do that?
