Can I install a preiously installed Windows 7 CD on a second PC?
Without a long and boring story, I let soeone who works for an ISP remove my Windows disc and reinstall a different Windows 7 OS without a key(not genuine). I have a second PC with a genuine Windows 7 OS CD with the original 25 letter key. Can I just install that disc and get it activated using that 25 letter key or must I buy a new Windows 7 CD??
