In some cases, when you attempt to upgrade to Windows 11, there’s an error that says your computer’s processor is not supported.
The most common reason for your system not meeting minimum system requirements to run Windows 11 is an incompatible CPU. Check the list of supported Intel processors and list of AMD processors to see if yours is included.
