**Hello **Dusan Pizarro Reyes,
I understand how frustrating this is that damaging the product key sticker can feel like hitting a wall, especially since that’s the only way to activate your Windows Server DSP/OEM package. Let me walk you through the right steps.
For OEM/DSP editions, the product key is tied to the physical Certificate of Authenticity (COA) sticker that comes with the media. If the sticker becomes unreadable, Microsoft cannot issue a new key directly, because the license is managed through the OEM channel.
Therefore I suggest you to contact:
- Reseller or distributor: Your first stop should be the store or partner who sold you the package. They are responsible for replacing defective or damaged COA labels. Be ready to provide proof of purchase and photos of the damaged sticker.
- Microsoft OEM Support: If the reseller cannot help, escalate to Microsoft Support under Windows Server → Licensing/Product Key issues. They’ll guide you on next steps.
- Manufacturer: If the license came bundled with hardware, the device manufacturer is the one authorized to replace the COA.
I recommend you to Keep the DVD and damaged sticker safe — they’ll likely be requested as proof. And also, have your invoice or receipt ready before contacting support. Don’t try to guess or reconstruct the missing characters; activation will fail.
