The market is just too small. There are articles calling the Surface Pro 3 too niche of a product. The Surface Pro 3 is a product that Microsoft sold $908 million worth in one quarter. The Zune was generating $85 million in revenue while it was dying off. In the VMS market the heavyweight, Avigilon, posted $271 million in revenue for all of 2014 and that was on much more than just VMS.
Free generates no revenue and it is unlikely to generate any significant demand for Windows, particularly when the vast majority of the VMS market already requires Windows to operate.

The also have developed somewhat of a PSIM in conjunction with NYC that they were advertising/had paid news stories a couple years ago. There was an IPVM story or discussion thread about it.

I don't think that MS could simply dev a free edition without going all the way and also dev a paid premium/corporate version. Including a VMS, just like they do Media Center, with a premium version of Windows might be a good idea, but that wouldn't generate any revenue. They would have to have a professional version with more capablilities in order to justify any dev time. In that case, it might be easier to buy out Genetec or the like to get the experienced devs.
