This gives you the flexibility to transfer and use the product key on any computer. Also, unlike a digital license, a product key is not tied to your hardware or Microsoft account. You can purchase a product key from an authorized retailer or Microsoft site. On the other hand, a product key is a 25-characters alphanumeric code that is commonly found on a physical copy of Windows or sent via email when you purchase a digital copy. You can obtain a digital license by purchasing from the Microsoft Store, upgrading from the previous version of Windows (such as Windows 7 or 8) to Windows 10 or a newer version, or using an OEM-installed Windows. When you install and activate Windows 10 or 11 on your computer, it creates a digital license for that specific hardware.
