I just want to know how can I 
 Windows 7 Pro X64 my laptop, so that the only thing 
 Windows 7 Pro 64 Bit is the windows itself, as if I have just 
 Windows 7 Enterprise Product Key my computer. I don't have any 
 Windows 7 Home Basic 64bit CD's, because windows 7 came with the 
 Windows 7 Enterprise Activation, so how can I do that?
