Windows Server Evaluation editions are intended for testing purposes and are time-limited. To continue using the same installation productively, the evaluation edition can be converted to a fully licensed version without reinstalling the operating system.
Microsoft supports this in-place conversion using the DISM tool, provided you have a valid product key for the target edition.
Once the target edition is known and you have a valid product key, you can start the upgrade. The value <TargetEdition> must be one of the supported editions returned by the DISM command.
Common target editions are:

Start the conversion with the following command. Replace <TargetEdition> with the desired edition and <ProductKey> with your 25-character Windows Server product key:
DISM /Online /Set-Edition:<TargetEdition> /ProductKey:<ProductKey> /AcceptEula
| Operating System Edition | Generic Volume License Key |
|---|---|
| Windows Server 2025 Standard | TVRH6-WHNXV-R9WG3-9XRFY-MY832 |
| Windows Server 2025 Datacenter | D764K-2NDRG-47T6Q-P8T8W-YP6DF |
| Windows Server 2022 Standard | VDYBN-27WPP-V4HQT-9VMD4-VMK7H |
| Windows Server 2022 Datacenter | WX4NM-KYWYW-QJJR4-XV3QB-6VM33 |
During the process, it may briefly appear as if progress has paused. This is normal. After the conversion completes, a restart is required to finalize the edition change.
