I am sure that is only there for legal reasons.
I have an insider view of the electronics world, I know that for a system to be fit for use in medical , nuclear, millitary or space service is needs to pass additional tests. Typical comsumer electronics will never have been tested to the level required. So the serious well behaved parts of the medical and nuclear sectors such as ABB, BNFL, Philips, Siemens, Westinghouse etc will not blindly trust microsoft XYZ to run a critical process. On the other hand some corner cutting bad guys in some rouge nation trying to make plutonium, build bombs or cheap pacemakers will feel no problem with buying an electronic game or normal PC (Saying its just for playing world of warcraft, honest !) before going off to do their unspeakable acts in some dark corner.
The latter group of people can not be delt with by a disclaimer, the only way to stop these bad guys is to prevent the export of electronic and computer goods to the nations where they lurk.

Diagnosed under the DSM5 rules with autism spectrum disorder, under DSM4 psychologist said would have been AS (299.80) but I suspect that I am somewhere between 299.80 and 299.00 (Autism) under DSM4.
