Now they've spent a sh!tload on manual fallback, and are preparing to pay ransom money for XP crap, and now the public embarrassment and loss of confidence to the public, perhaps they could actually spend funds on UPGRADING the systems.
Yeah, yeah, I know some old physical kit may well have some "turnkey" XP back end that can't be decoupled from it. If it hasn't reached the end of life, isolate those consoles from any network and superglue the usbs and CDs. For anything else that isn't attached to your multi-million dollar MRI machine that is currently mid-life, UPGRADE.
(Yes, I know what it's like ferreting out old applications, asking the vendor if there's an upgrade, purchasing and implementing said upgrades (or writing new code), and migrating data, but that can all be done if tackled incrementally and thoroughly. And sometimes the solution is better, if you actually spend some time on requirements analysis first, ha! ha! ha!).
