Hello，

Thank you for posting in the Microsoft Community forum.

If your Windows 11 Pro product key is unreadable due to mechanical damage, please try the following steps to query:

1. Try logging into your Microsoft account and see if you can find information about the activated product on your account's device information page.
2. If you purchased your Windows 11 Pro product through a retailer, it is recommended that you contact them directly for assistance. They will ask you to provide proof of purchase and COA barcode, please prepare it in advance.
3. Contact Microsoft Volume License Key Customer Support for enquiries, providing your COA barcode and proof of purchase to verify your information:
