How to Convert Windows Server Evaluation to a Licensed Version? 

You can freely convert between Windows Server 2025 | 2022 | 2019 | 2016 | 2012 R2 Evaluation version to Retail/Volume/OEM Licensed version. The edition remains the same during this conversion. If you are starting with an evaluation version, convert it to the retail version first, and then you can inter-convert as described. To do this, from an elevated command prompt, run:

slmgr /ipk <key>

Where <key> is the appropriate volume, retail, or OEM product or license key.

Open PowerShell/Terminal as Administrator and write and enter: slmgr /ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

After inserting the license key successfully, write this command for activation: slmgr /ato

Note: You will require a brand new, genuine license key for activating your server. Ensure you have it ready. If not, you can purchase one from our store at up to 80% off the MRP. Please browse through our site to find the product you need. Thank you! 

If it doesn't work and getting an error like: Error: 0xC004F069 and 0x2a 0xc004f069 or Error 1168 the specified product key could not be validated, You need a Retail product key (which you will get from us if purchased from our store) and use DISM command to upgrade Windows Server Edition from evaluation edition to Standard or Datacenter edition.

If the server is running an evaluation version of Windows Server as Domain Controller, you can convert it to a retail version as follows:

For the evaluation version of Windows Server Standard, you can also convert to the retail version of Windows Server Datacenter in one step using this same command and the appropriate product key. For more information about Dism.exe, see https://go.microsoft.com/fwlink/?LinkId=192466.

In our experience, this issue arises only when the server was installed using a Microsoft-provided Evaluation License Key. If the server was installed without any key, the activation process is simple. Just use your purchased license key, and it will activate instantly.
