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