How to Install and Activate

1. Download the Windows Server 2019 ISO from the Microsoft Evaluation Center and install Desktop Experience or Server Core.
2. Convert the evaluation edition before activating: DISM /Online /Set-Edition:ServerDatacenter /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX /AcceptEula, then restart.
3. On a full (non-evaluation) installation, run slmgr /ipk with your key, then slmgr /ato.
4. Activation is online, so make sure the server is connected to the internet.

Troubleshooting Tips

• Edition mismatch (0xC004F069): the installed edition isn't Datacenter. Convert with DISM.
• KMS error 0x8007232B: install your key with slmgr /ipk before activating.
• Hardware changed: contact our support team.

Do You Need CALs?

Yes. Every user or device that connects to Standard or Datacenter needs a Windows Server CAL. Remote Desktop users also need RDS CALs: RDS User CALs or RDS Device CALs.
