How to Find Your Windows 11 Product Key 

1. Pre-installed Windows 

If your PC came with Windows 11 pre-installed, the product key is usually embedded in the device’s hardware, known as BIOS or UEFI. It activates automatically when connected to the internet, so you typically won’t need to re-enter the key.

For those who purchased Windows 11 online, the product key is sent via email. Be sure to save this email or add it to a secure location, as it will be required for activation. 

3. Physical Copy 

If you bought a physical copy of Windows 11, the product key will be found inside the DVD case or on a label on the packaging. 

4. Command Prompt or PowerShell 

If you’ve lost track of your product key, you can retrieve it from an activated system:

• Open Command Prompt or PowerShell as an administrator. 

• Run the following command: wmic path softwarelicensingservice get OA3xOriginalProductKey. 

• Your product key will be displayed on the screen (only works for OEM-installed keys).
