I already have Windows 11 installed but it's not activated and I have a product key.
Press Windows key + I, or right-click the Start button and select "Settings".
Click on "System" in the left sidebar, then scroll down and click on "Activation".
Click on "Change product key" next to the activation status.
Type your 25-character Windows 11 product key in the format: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
Click "Next" and then "Activate". Windows will verify your key and activate automatically if valid.
