Well, I will tell you that some practices have enough with Windows 10 "we're here to help you" hell and have wiped machines and installed Win7. I'm sure Sandeep or James will be glad to earn their keep fixing what MS breaks but across a network, the business math of that sucks.
To minimize attack surface and maintenance costs, some practices are wiping old machines and installing graphical Linux desktops, and using terminal services.
Bottom line from a business perspective, how much do you want to pay MS for the privilege of breaking your network and taking your practice offline.
