Manufacturer's T's&C's...
Just need to point out that their kit is for private LAN use only. The equipment is not to be used on LAN's connected to a WAN.
IMHO development of this kind of kit - surmounting the medical technicalities is far more important to all parties than its ability to work with, say Windows 10.
If the developers were expected to provide their kit for systems loaded with Win 10 then they'd either be spending a lot of development resources ensuring that Win 10 did not demand an update halfway through a critical medical event, or they'd have to put a disclaimer in their T's&C's about it not working entirely flawlessly using Windows 10 as the host Operating system.
Which would you prefer at the side of your hospital bed? A DOS screen, or a W10 one?
