Hello Kris K,
This case is directly tied to licensing rules for Windows Server 2025 Standard OEM. Unfortunately, the situation you describe—damaging the physical product key sticker—is a hard stop in terms of recovery. OEM licenses are bound to the hardware they ship with, and the product key is only provided once, on the Certificate of Authenticity (COA) label or embedded in firmware if it was preinstalled. Microsoft does not reissue or replace OEM keys because they are the responsibility of the hardware vendor.
If the key was embedded in the system firmware (common with client editions, less so with Server), you can check by running:
wmic path softwarelicensingservice get OA3xOriginalProductKey
If nothing is returned, then the key was only on the sticker. In that case, the only legitimate path is through the vendor who sold you the hardware. Microsoft Support will confirm the OEM licensing terms and redirect you back to the vendor, since OEM keys are not transferable and cannot be reissued by Microsoft directly.
If the vendor remains unresponsive, your only compliant option is to escalate through their support channels or purchase a new license through Volume Licensing or a trusted reseller. Attempting to bypass activation or use third‑party tools is not supported and will put the system out of compliance.
I know this isn’t the answer you were hoping for, but with OEM Server licenses the vendor is the sole authority for replacement. If the sticker is damaged beyond recognition and the key isn’t embedded in firmware, Microsoft cannot provide a new one.
I hope you've found something useful here. If it helps you get more insight into the issue, it's appreciated to accept the answer. Should you have more questions, feel free to leave a message. Have a nice day!
Domic Vo.
