In the past, old versions of Windows were often considered superior because they stopped changing and just kept working. Today, that strategy is breaking down because attackers have a lot more technology available to them: a huge database of exploits, faster computers, IoT botnets, and so on. I suspect we're going to see a shift in the type of operating system hospitals run. It might be Linux or a more hardened version of Windows. Either way, the OS vendor should provide all security infrastructure, not a third party like Crowdstrike, IMHO.
