I just want to
Microsoft Windows 7 Home Premium how can I
Windows 7 Starter 64 Bit Key my laptop, so that the only thing remaining is the
Windows 7 Pro Update Key itself, as if I have just bought my
Windows 7 Enterprise X86 Key. I don't have any installation CD's, because windows 7 came with the
Windows 7 Professional 64 Bit Key, so how can I do that?
