Hello THOMAS EVERTSSON,
I completely understand how frustrating it is when the product key gets scratched too hard and becomes unreadable. The good news is, you won’t lose your license—there are official ways to fix this and get your Windows 11 Pro activated.
Your product key is important, but Microsoft can also verify authenticity through the COA label, barcodes, and packaging. If the key can’t be read, Support can confirm your purchase and issue a replacement.
Here’s what you can do:
First, check if your PC is already activated. Go to Settings → System → Activation. If it says activated with a digital license, you don’t need the printed key.
If not, contact Microsoft Support with clear photos of the COA label/box and your proof of purchase. They’ll validate and provide a new key.
If you bought it from a reseller, you can also reach out to them with the same documentation.
Avoid third‑party “key finder” tools—they won’t recover a scratched key and may expose you to risks. Only Microsoft or authorized resellers can issue replacements.
The quickest solution is to open a support case with Microsoft and submit your photos and receipt.
This way, your license is protected, and you’ll be back up and running with Windows 11 Pro in no time.
Please let me know if any of these steps help resolve the issue. If you find this answer helpful, feel free to hit "Accept Answer" so others can benefit too 😊.
