All of those machines will have to be upgraded at some point. Some of them are connected to very large, expensive legacy pieces of hardware, such as MRI machines or X-ray devices, which cannot cope with the newer versions of Windows software. In a large portion of the cases, perhaps half, that is the reason the Windows 7 computers are there. That involves either the manufacturer of the machinery upgrading its systems or else, when it is time to replace the X-ray or MRI facility, the replacing of the client machines also. However, you can take mitigating actions to prevent against it. Windows 7 is one risk of many. It is not the sole reason this attack happened. Certainly, upgrading software across the network, including Windows, is one of the things that should be done, but there are many things that have to be done-----
