Hi Parras, Hazel,

Microsoft does not publicly list Multiple Activation Keys for Windows Server 2025 because these keys are proprietary and bound exclusively to your organization's specific Volume Licensing agreement. Providing or seeking public MAK keys violates software licensing terms and security protocols. To retrieve your keys, your billing or global administrator must log into the Microsoft 365 admin center, navigate through the Billing section to Your products, and open the Volume licensing area. The Downloads and keys interface will display the exact activation strings allotted to your enterprise.

Once you have your authorized MAK, you can apply it to your server using the built-in Windows Software Licensing Management Tool. You can achieve this by opening an elevated command prompt and executing the script located at C:\Windows\System32\slmgr.vbs followed by the /ipk switch and your retrieved product key. If your infrastructure relies on isolated networks where external activation to Microsoft servers is blocked, the recommended alternative is to deploy a local Key Management Service host. This allows your internal servers to activate offline using public Generic Volume License Keys and that exact same licensing management script.

Hope this answer brought you some useful information.
