Window Server 2019 Activation Failed (Error:0x8a010001) - [Solved]


launch cmd as administrators on a problematic machine, then run command slmgr /dlv


Activate WS 2019 failed by command dism /online /set-edition:ServerStandard /productkey:*** /AcceptEula



Before activate the evaluation version, you have to use a KMS client key to convert the evaluation version to retail version. Then use the command slmgr /upk to uninstall the KMS client key and slmgr /ipk to install your key. The KMS client key is published in the website Key Management Services (KMS) client activation and product keys for Windows Server and Windows | Microsoft Docs.



1.Please backup important data before making changes


2. From the official article below, usually the evaluation version can be directly converted to a retail version. And if we want to convert to volume-licensed version, we’d better convert to retail first, and then convert the retail version to volume-licensed version.


3. Here let’s proceed with the help of Windows Server 2019 KMS Standard client setup key: N69G4-B89J2-4G8F4-WWYCC-J464C.


4. Please run Powershell as admin, run the command below:


dism /online /set-edition:ServerStandard /productkey:N69G4-B89J2-4G8F4-WWYCC-J464C /AcceptEula


5. After the command completed, please run the commands below to install your key

Slmgr /upk

Slmgr /ipk <Your product key>

Slmgr /ato
