It is my experience that hospital(s) do not have the budget for Windows 10 across their entire network.
One way I can think of to disrupt this process is partnering with a new medical device company which is accelerating sales to hospitals. Last time I had this conversation the promising ones were all Chinese, wanted investment solely for development of algorithms under Chinese jurisdiction as part of terms of investment, and carried all the usual IP theft and legal risks you can imagine. Israel has some med tech startups too but they wanted to source talent from within their country and their due diligence seemed to be more of an intelligence gathering operation.
I moved on to working in finance. I don't know what ended up happening to that startup. I left after the paychecks stopped coming.
