I thoroughly enjoyed your reply as it offered useful information while also making the original commenter look silly.

I did not enjoy your reply as it did not add anything useful, and overlooked the fact that the comment you considered silly was intended as a joke. Dismissing something funny as silly is a bit like dismissing water as being moist. ;)

On a Windows/Hospital related note, I heard this antecdote in a class, any confirmation if true or source? Seems very plausible and likely.

During an operation, one of the OR monitoring devices went down because it was running on Windows and was neglected for some period of time, causing Windows to do an automatic reboot for a "Critical Windows Update."

Of course, seeing a necessary piece of OR equipment go down due to a Windows setting didn't make anyone happy, so the response was to remove automatic update from all of the Windows boxes in the Hospital. Not just mission critical ones, all of them: Secratary's machies, Nurse's machines, IT machines, etc. Fast forwood some months/years, no manual updates were done either, and with automatic ones turned off, a virus came across through a worker's computer and wiped out everything.

True or not, I still think it is a good story for how not to handle security issues.
