Hello Everton Thompson
You can purchase a license/product key for Windows Server 2016 from the Microsoft Store or from a Microsoft authorized reseller. Once you have purchased the license/product key, you can activate your evaluation copy by following these steps:
- Open the Server Manager on your Windows Server 2016 machine.
- Click on the "Local Server" option.
- Under the "Properties" section, you will see an option to "Change product key". Click on it.
- Enter the new product key that you have purchased and click on "Activate".
Your Windows Server 2016 machine will now be activated with the new product key.
Best Regards,
Hania Lian
