I do not think windows is the problem here. The problem is that equipment that is critical infrastructure being connected to the internet, imo. There is little reason for a lot of computers in some settings to be connected to the internet, except for convenience or negligence. If data transfer needs to be done, it can happen through another computer. Some systems should exist on a (more or less) isolated network at best. Too often we do not really understand the risk of a device being connected to the internet, until something like this happens.
