Enter the product key that came with your retail purchase or legal download of Windows 7. If Windows 7 came as part of your complete computer system, enter the product key you were given as part of that purchase.
Note: If Windows originally came preinstalled on your computer and you're now completing a new install after a hard drive replacement, your product key is probably located on a sticker attached to the side, back, or bottom of your computer's case.
Important: You may be able to avoid entering a product key at this point but you will eventually need to do so in order to continue using Windows 7. I highly advise that you enter your product key here and choose to Automatically activate Windows when I'm online.
