I would personally use an enterprise Linux distro for something like health records and other critical data, but you can Windows 10 similar to how you use Windows 7, and it's a faster OS. You just need to spend some time to get your settings in place. I was in the same camp of you as Windows 10 vs 7 until I saw how much Windows 10 sped up an old machine of mine.
