Hello,
If Windows Server 2019 is not activated, it will continue to function normally for a grace period of 180 days. After the grace period expires, the server will enter into a reduced functionality mode, which means that some features will be disabled, and the server will only be able to perform basic functions. It is important to activate Windows Server 2019 to ensure that it continues to function properly and to receive security updates and patches.
You can buy the product key from Microsoft Store or an authorized reseller.
Best Regards,
Hania Lian
