A license or key for any other version of Windows 10 will not validate Windows 10 Pro. If you don't own Windows 10 Pro, but want to upgrade to it, you can purchase a key from Microsoft. Digital Windows 10 Licenses/Embedded License A digital license is a virtual product key. If you previously upgraded from an older version of Windows to Windows 10, you have what is known as a digital or embedded license. That means the Microsoft servers already know you have a Windows 10 license for that laptop, which is linked to serial numbers of several pieces of hardware they identified in your laptop and it will be automatically validated by Microsoft without you putting in an actual product key. While you do not need a physical product key in this case, you do need to know if you own Windows 10 Pro or Windows 10 Home as the installed version on the hard drive must match the version you own.
