You purchased directly from Microsoft’s site: Microsoft will send you a confirmation email after you purchase, and the product key should be in that email. Keep all the documents that came with your PC and don’t take off any stickers that have the product key until you’ve used it. Typically, the product key is included on the Certificate of Authenticity, usually a sticker directly on the PC itself, or sometimes on the back of the manual. You bought a PC with Windows 10 already downloaded: This is fairly common, and in these cases the packaging and manuals are particularly important.
