One of my responsibilities was to serve as admin for our campuses digital signage system. It used windows based machines. The cost of the Windows OS was trivial compared to the cost of the hardware and the license for the digital signage software. it also helped that if need be these systems could be managed with our existing toolset such as SCCM and remote desktop. and if we needed to do something that the Digital Signage software could not do for special occasions if there was a windows app for it, it was that simple.
