If blocked from the internet I see no issues. IMO, every old Windows System needs to attach to their own "personal" router that has a robust firewall. or maybe a "PI" type board acting as a router. But from what I have seen, the largest abusers are in the Medical Industry. For example, hospital's IT are far from a priority and its only purpose is to keep things running, not security. Add to that Medical Software is insanely expensive, making companies like SAP and Oracle jealous of what these companies can get away with. And you have the fear factor in medical, if an upgrade fails, someone could die. Thus releasing the Lawyers.
