Don't use WINDOZE!
The answer is: don't use Windows for vital services such as hospitals! Most IT departments hire people who know nothing else. The main problem is that the government always hires the wrong IT companies for its large projects, companies run by megarich businessmen who know nothing about IT rather than smaller companies run by mavens. That is why the NHS computer services have more holes in them than a Gruyère cheese. Remember the millions wasted by the NHS trying to computerise its entire system, only to discover that they were incapable of doing it? The NHS needs its own proprietary operating system that cannot be penetrated by cyberterrorists.
