Sorry to bump an old post, but I'm just updating for anyone who comes across this from Google or whatever that is interested in a MK96. It works great on Windows, zero problems at all. It's the best keyboard that I've personally used! I've only had a Model M, FK2001, AT101w, and this takes the cake by a good margin, at least for my likings. Because there's so little info online, keep in mind that the big drawback with this board is that the little nubs on the F and J keys are instead on the D and K keys board this board. I'm a noob with keyboards so I don't know if you can replace the keycaps to get around this, something to keep in mind regardless.
If anyone has questions about the board, I'll do my best to answer.
Also, if anyone has experience with MK96s and can tell me if I can swap out keycaps on it, I'd appreciate some info!
