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.
