Thanks. I've got a native W10 installation on my i7 2012 Mini, so it should upgrade then. Phew.
I was stunned to find my 4.5 year old dual processor 16 core Xeon is not supported and so the chance of a 9 year old i7 being supported must surely be zero?
I know MS only make money from new machine sales but if they actually push ahead with not supporting hardware more than 4 years old regardless of performance it cannot do anything but drive substantial numbers to other platforms. If I cannot use my current software development platform for Windows 11 I will seriously review whether Windows 11 is a platform worth supporting for my software. Windows is a fairly minor platform for scientific and engineering software and so if they are going to follow Apple with their support then goodbye (perhaps). I suspect they are going to back away from this (they have removed the Windows 11 compatability tool on their website) but in some ways the damage has been done given they considered doing it. They used to be extraordinary in the way maintained backward compatability but how they have changed.
