How to Convert Windows Server Evaluation to a Licensed Version? 

You can freely convert between Windows Server 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!
