How to Find Your Windows Product Key

[javajolt]

In this video, I show you several tools (including the Command Prompt, PowerShell, NirSoft's Prodkey, and finding the Certificate of Authenticity) to find the product key for Windows. At least one of these methods can be used to recover the key for Windows 10, 8, 7, and the server versions of Windows. Though it's hidden in the Window's Activation screen and inaccessible in your computer's BIOS, you can retrieve an OEM key from the BIOS or UEFI, or obtain it from the registry.

In case you want to copy and paste the commands, here is the one for the Command Prompt:

wmic path softwarelicensingservice get OA3xOriginalProductKey

and here is the one for PowerShell:

(get-wmiobject -query ‘select * from SoftwareLicensingService’).OA3xOriginalProductKey
