Never thought I would get to say that on /.! I work in a hospital and set up PCs for Cath-lab, surgical anesthesia monitors and stuff all the time. As far as this goes the hospital usually just buy the seats (or whatever) for the software and you install it. All the software like this comes with explicit and unambiguous instructions for directory and file type exclusions. Right or wrong, the software will run fine if this is done correctly - it will crash if it is not. First, all the posters are right, windows is crap and shouldn't be used. But it is chicken and egg - the hospitals buy it because that is what all the vendors write their apps for, and the vendors code for Windows because that is what hospitals buy. I am stuck with it. There are a few vendors that run Linux end-to-end, but it is rare.
