There will be ways to capture it anyway. Probably specific software designed for GPU capture, since that’s how these apps “prevent” capturing, using GPU trickery.
Simplest way is a Windows VM and screen capture in the OS running the VM. Obviously next step for Microsoft is to detect and block Windows VMs, good luck to them with that.
The announcement from MS and the linked article both also mention this, though they recommend the real analogue hole: a separate camera pointed at the screen.
