Re: Windows 11 Beta
Again, Windows 11 can use legacy drivers, Microsoft has admitted that even the release build will allow it.

But Microsoft won't tech support the systems using legacy drivers, and that tech support includes security profiles which Win11 promises to improve over all previous versions on Windows.
Microsoft is cutting their foreseeable costs by saying "Yes, you can run Windows 11 on the older gear...but you're on your own". Why? Because Windows 11 is / will be marketed as more secure and (hopefully) more stable thanks to that added security, and people will inevitably install Win11 on older hardware...and then, also inevitably, some of those legacy hardware users will call out Microsoft to complain when their system got spyware, adware, a trojan or worse, ransomware.
And then Microsoft will say "Remember when we told you that installing on your older system isn't our problem?"
If Microsoft said they will support hardware that can't be secured under their new, or future-proposed, security models, they would take the heat when some of those old systems still get their security broken.
