My device couldn't find the windows product key.

Your Windows 11 Pro license is embedded in the motherboard firmware, so it will not be lost. To retrieve the product key and reactivate Windows, please follow our official guide: https://service.geekompc.com/faq/how-to-check-the-activation-key-of-windows-system-on-a-computer/

If you still cannot activate the system, please contact our customer support and provide your device SN code. We will check the corresponding product key for you.
