Hi Jean,
I'm Ahmed and I am here & happy to help.
Sorry for having this issue.
Unfortunately, this processor does not meet with Windows 11 requirements. As of now, there are no plans announced to support this processor in future updates of Windows 11
Windows 11 minimum requirements: https://support.microsoft.com/en-us/windows/win...
I hope this helps! Let me know if you have any further questions or concerns.
Best regards,
