You misunderstood me: are we assuming that the Microsoft list of supported processors represents all the CPUs that can run Windows 11, rather than the list that Microsoft supports (meaning they promise it works, promise it will continue to work)
These at least to me seem like completely different things (and have been in the past).
As an example: Windows 10 is not officially supported on Sandy Bridge CPUs like the i7-2600K but it runs just fine.
