Hi, I am Dave, I will help you with this.
Windows 11 minimum system requirements indicate an 8th gen Intel processor and you have a 7th gen processor, they indicate it is not about the speed or strength of the processor, it is about the security features supported on the processor.
They previously provided a registry edit method to install Windows 11 on an unsupported processor, but when they released version 24H2 of Windows 11, they seem to have removed the web page explaining how to use the registry edit.
