    The Product Key is encoded in your computer, in BIOS. To access it, you will have to use a third-party software, like Produkey or Show Key Plus.

    A Windows product key is a 25-character key that tells Microsoft that your Windows operating system is authentic. The way you find it will depend on how you received the product key initially, but if you can't find it, I recommend Magical Jelly Bean, which is a product key finder.
