Applies to Windows 7, 8 and 10: Your product key depends on the type of Windows version you bought.
If you bought 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 upgraded Windows, the Original key will be the key installed prior to the upgrade. NB if you upgrade to Windows 10 for free, you'll receive a unique ‘digital entitlement’ instead of a product key. The key displayed will be a generic key in that case.
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 OEM key will display the key in the case of the former, or whether your PC was built for Windows Vista or Windows 7.
Apart from the key, the associated Edition of each key is displayed below it.
Information displayed: Product Name: The current version of Windows installed
Product ID (PID): A PID is created after a product is successfully installed. PIDs are used by Microsoft Customer Service to help identify the product when customers engage Microsoft for support.
Installed key: The generic product key issued by Microsoft and used by Windows 10 (varies based on the edition installed).
Original Key: Your computer’s Windows 7, Windows 8 / 8.1 “Retail or OEM key” before upgrading. If you have a “Retail” or OEM System Builder key, use this product key if you want to re-install your original version of Windows.
OEM Key: OEM SLC key installed by the computer manufacture. OEM SLC keys are not unique and cannot be used to re-install your earlier version of Windows. You need the product key located on the COA / Product key sticker located on your sticker to re-install Windows 7.
Note: Click the Version link to toggle between light and dark mode skins
Even if you have not upgraded to Windows 10 ShowKeyPlus will display your Windows 7 product key.
ShowKeyPlus will also retrieve Windows 8 / 8.1 product keys as shown in the screen shot below. If your PC came with Windows 8 or 8.1 pre-installed ShowKeyPlus will indicate that information also.
If you have more than one computer and you need a quick way to find which retail product key was used on each machine: Open a command prompt (run as administrator) and type: slmgr /dli and tap the enter key.
If you are curious as to what your Windows 10 product key is and do not want to use ShowKeyPlus: Open a command prompt (run as administrator) and type: wmic path softwarelicensingservice get OA3xOriginalProductKey and tap the enter key.
