Thanks I got that, but its just come to light today for me at least, that it still won't be good enough for proper all round hardware based security. Look at these articles here & here. MBEC & HVCI are lacking on all non supported processors, in fact it seems that even Ryzen 2000 series are lacking it too! but why are they on the list of supported processors? We can speculate all we like but I think MS are scared of more backlash from the market for how stict the CPU list is already. I'm just going to have to budget up & rebuild that system with something more modern. In the meantime that system can be a historical curiosity in the great world of PC history!
