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