x8 WINDOWS 10/11 PRO KEYS

I encountered the same issue after upgrading to Windows 11. A useful method I found was using a KMS activation tool and you can visit download kms tools for a solution that works with Windows 11. The tool is easy to use, and the website provides detailed instructions on how to get everything set up. Make sure to follow the steps closely, and it should activate your Windows 11 without any problems.
