How to Change Your Product Key in Windows 11
You change your Windows 11 product key to activate a different edition of Windows or to switch from a generic key to a retail one.
A Windows product key is a unique 25-character code that verifies your copy of Windows is genuine and unlocks its full features.
This process is straightforward and can be completed directly within Windows 11 Settings, even if you have a digital license for an upgrade. We’ll show you exactly how to input your new 25-character key.
Change the Product Key Using Windows Settings
This is the easiest way to change your product key:
- Open Settings: Press the Windows key + I on your keyboard. Or click the Start button and select the gear icon (Settings).
- Go to System: On the left menu, click System.
- Click Activation: On the right side, find and click Activation.
- Change Product Key: Look for the Change product key button and click it. If you have Windows 11 Home, you might see Upgrade your edition of Windows first. Click to expand, then find the change key option.
- Activate: Click the Activate button to finish.
- Close Settings: Click Close when done.
Change the Product Key Using Command Prompt
If you prefer using commands, you can change your product key this way:
- Open Windows Terminal (Admin): Press Windows key + X and choose Windows Terminal (Admin). Or search for “Windows Terminal” in the Start menu and run it as administrator. Learn more about opening Windows Terminal. ⚠️ Admin privileges required

slmgr /ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX - Press Enter: Hit Enter to run the command.
