Dear Manuel Munoz,
Thank you for reaching out regarding the issue you're experiencing with activating your Windows license.
We understand that the activation process is not completing successfully, despite entering the product key. This can happen for several reasons, including mismatched Windows editions, network connectivity issues, or the key being previously used on another device.
To begin troubleshooting, please confirm that the edition of Windows installed matches the license type (e.g., Windows 11 Pro). You can check this by going to Settings > System > About. Next, ensure your device is connected to the internet and try activating again via Settings > System > Activation > Change product key.
If activation still fails, we recommend running the Activation Troubleshooter from the same menu. This tool can automatically detect and resolve common activation errors.
If the above response helps answer your question, remember to "Accept Answer" so that others in the community facing similar issues can easily find the solution. Your contribution is highly appreciated.
Best regards,
