Unfortunately there actually ARE hospitals using Windows servers for
their critical infrastructure. I've seen them, and I've seen what
happens when they blue-screen.
I've heard stories about banks that have migrated their transaction
processing from IBM mainframes to Windows, but they may just be stories.
I have no idea what railroads are using.
The US Navy at one point was switching from Unix to Windows. They had
major problems with this on the USS Yorktown, and had to tow it back to
port. I don't know whether they've completed the switch.

Redman said that NT had been chosen for political rather than technical
reasons. Where's the line between stupidity and treason?
It's been more recently reported that the British Royal Navy is using
Windows to run their nuclear submarines.
One of the best reasons not to use Windows for critical infrastructure
has nothing to do with flaws in Windows. Over and over again I've seen
people have failures of Windows-based systems that were intended to
serve a single purpose, such as control the HVAC systems for a large
building, because some damn fool thought it would be a good idea to
install a bunch of extra software on them, including games, and various
random software downloaded from the Internet.
