Why use Windows? It's easy and inexpensive to get developers who are familiar with the platform. You can leverage a lot of tools that already exist for the platform. You get a lot of hardware support "for free" using manufacturer-provided drivers. Medical device manufacturers are for-profit entities looking to make a profit. If using Windows makes it easier to make a profit then they'll use it. If that's problematic to society, from a security perspective, then regulations should be put in place to put make security costs impact the manufacturer's bottom line. Personally, I'd like to see pentesting as part of device certification requirements.
