To avoid frustration with the server GUI, it's beneficial to learn how to activate the Windows Server 2019 license through alternative methods such as the command line or Key Management Services (KMS). Errors and key rejection can happen, often for no apparent reason. There are also times when entering a valid key from the Volume Licensing Service Center (VLSC) will not work.

With multiple server workloads, it's not efficient to log in to each machine and manually activate them. Windows Server 2019 requires license activation after 180 days, otherwise the system will shut down.
