How do I activate Windows 7?

Okay so i custom built my computer and I booted from a usb with windows 7 on it and I went through the installation and setup and everything and forgot I needed a product key.

Now I actually need to activate it. My question is can I go to best buy and buy windows 7 Home premium sp1 with the disc and product key and use the product key to activate windows 7 already installed on my computer.

    If it is the same version, yes.
    Where did you get the version you installed?
  4. yeah that should work unless the usb had an OEM copy on it other wise it will be fine.
    allthough you may need to do a phone activation after trying the product key
  5. May I ask why you have not activated windows 7 on the machine.
    Are you saying that you have used the install, and activation key on another system.

    If that is not the case then i`m a bit worried.
    Because you could just pay for a new licence key for windows 7.
    And by asking if you get windows 7 service pack one and it will activate windows 7.

    Even if you bought windows 7 as a file, or image to download and burn to a dvd or usb stick.
    If legit you would of been e-mailed the activation key.
    So it`s not a case of forgetting is it, unless you have used the key already on another setup.

    I suspect the key has already been used or it is a pirate copy. So a service pack is going to check if the windows 7 is activated first.

    And of course it has to be the same family type.
    Based on the key.
