The OEM key will display the key in the case of the former, or whether your PC was built for Windows Vista or Windows 7.Īpart from the key, the associated Edition of each key is displayed below it. If you bought a new PC running Windows, the product key will be pre–installed on your PC and the key will be included in the firmware in the case of Windows 8 or 10 - or as an OEM marker, in the case of previous versions. The key displayed will be a generic key in that case. NB if you upgrade to Windows 10 for free, you'll receive a unique ‘digital entitlement’ instead of a product key.
If you upgraded Windows, the Original key will be the key installed prior to the upgrade. This applies to OEM System Builder keys as well. If you bought Windows from an authorized retailer, the product key will only show as the Installed key. Your product key depends on the type of Windows version you bought.
