ShowKeyPlus is a free portable windows product key finder and validation checker. If you purchased Windows from an authorized retailer, the product key will only show as the Installed key. This applies to OEM System Builder keys as well. If you purchased a new PC running Windows, the product key will be included in the firmware in the case of Windows 8 or 10 – or as an OEM marker, in the case of Windows Vista or Windows 7
Apart from the key, the associated Edition of each key is displayed below it.
Should you have a backup which includes a Windows folder, the key from that installation (as well as the previously installed key, if that installation was an upgrade), can be retrieved using the Retrieve key from backup link.
In order to verify the edition your key is associated with, use the Check product key link to confirm.
