How to Find Your Product Key in Windows 11
You find your Windows 11 product key using the Command Prompt or PowerShell to reveal the 25-character code that proves ownership of your operating system.
This product key is a crucial identifier for activating your Windows license with Microsoft, especially when you need to reinstall or transfer it to new hardware.
While many modern PCs utilize a digital license automatically linked to your hardware or Microsoft account, knowing how to access your traditional 25-character key remains important.
For example, if you bought a physical copy of Windows 11, your key might be on a sticker or in your purchase confirmation email, but this guide focuses on retrieving it directly from your current installation.
You can find your Windows 11 product key using Command Prompt by typing wmic path softwarelicensingservice get OA3xOriginalProductKey, or by using the ShowKeyPlus app from the Microsoft Store. If you upgraded from Windows 10, you likely have a digital license and don’t need a physical key.
Where to look for your key
Your Windows 11 product key is usually found on a sticker on your new computer, in the box if you bought it from a store, or in an email if you bought it online.
- New computers: Look for a sticker on the back or side of your PC. It might also be on the box or a certificate included with your purchase.
- Authorized retailers: Check the physical box or the card that came with your purchase.
- Digital copies: Check the confirmation email you received when you bought the software.
- Upgrades: If you upgraded from an older version, you likely have a digital license instead of a key, which activates automatically.
Using Command Prompt to find your OEM Key
If your PC came with Windows pre-installed, you can find its product key, known as an OEM key, using the Command Prompt by following a few simple steps.
Note: This step requires administrative privileges.
- Click the Start menu and type cmd.
- Right-click Command Prompt and select Run as administrator.
- Type the following command and press Enter:
wmic path softwarelicensingservice get OA3xOriginalProductKey - If a key exists, it will appear below the command.
Checking status with slmgr
You can also check your activation status using the slmgr /dli command. This displays your license type and a partial product key. It helps you see if you’re using a Retail, OEM (Original Equipment Manufacturer), or Volume license.
Using an app to find your key
A free app from the Microsoft Store can easily show you your Windows 11 product key if you can’t find it elsewhere.
- Click the Microsoft Store icon on your taskbar.
- Search for “ShowKeyPlus” and press Enter.
- Click the Get button to install the app.
- Once installed, click the Open button.
- The app will automatically display your product key on the screen.
Warning: Avoid third-party “key finder” websites. These often contain malware. Only use trusted tools from the Microsoft Store.
Activation Troubleshooting
If Windows is not activated, use the official Microsoft Activation Troubleshooter. This tool helps fix issues caused by hardware changes, such as replacing a motherboard.
Summary
Finding your Windows 11 product key is usually simple once you know the right places to look, whether it’s on your PC, in an email, or stored digitally.
Do I need a product key if I upgraded from 🪟 Windows 10?
No. If you upgraded from Windows 10 to Windows 11, your device is granted a digital entitlement. This license is tied to your hardware ID and Microsoft account, meaning Windows will activate automatically without requiring a 25-character product key during reinstallation.
Why does my computer say ‘Windows is activated’ but show no key?
This happens because your system is activated via a digital license. The activation status is stored on Microsoft servers linked to your hardware. You do not need a physical key because your computer is recognized as a genuine device based on its unique hardware signature.
Can I find my product key if my motherboard was replaced?
If the motherboard was replaced, the original OEM key embedded in the UEFI firmware may be lost. If you had a retail license, you can re-activate Windows by signing into your Microsoft account and running the Activation Troubleshooter to transfer the license to the new hardware.
