Hi,

I am having issues converting my server 2025 core eval to std with a valid license. None of the dism commands are working or slmgr /ipk. Is this conversion even possible?

DISM /Online /Set-Edition:ServerStandardCor /ProductKey:REALKEY /AcceptEula

Deployment Image Servicing and Management tool

Version: 10.0.26100.5074

    AFAIK, the issue you are encountering is a limitation with the Server Core evaluation media for Windows Server 2025. Unlike the Desktop Experience version, which allows for a straightforward edition upgrade, the Core Evaluation image lacks the necessary license components to transition directly to the retail or volume license Standard Core edition. The error code 0x80070490 indicates that the installer cannot find the required license file because the evaluation image is stripped of the retail metadata needed for the Standard SKU.

    The in-place conversion path that should work for Server Core Evaluation is moving to the Datacenter Core edition. When you run the target edition query, you will likely see that ServerDatacenterCor is listed as a valid destination. If you need to use the Standard edition, you would have to perform a clean installation using the non-evaluation retail or volume licensing ISO. Using the non-evaluation media from the start bypasses the lockdown on edition transitions inherent in the evaluation-specific binaries.

    If you want to verify the specific upgrade paths available to your current installation, you can run the following command to see if the Standard edition is even listed as a possibility.

    DISM /Online /Get-TargetEditions

    If ServerStandardCor is not in that list, the system will continue to reject any attempt to force the product key.
