Whilst I could not find an explicit confirmation that the Robotic Development Kit works with Windows 10 IoT, I did find a couple of articles that heavily implied it does.
Firstly, the Robotic Development Kit uses a board called UP, which is compatible with Windows 10 iOT.
"UP supports Ubilinux (a customized Debian distribution), Yocto, Ubuntu, and Microsoft Windows 10 IoT Enterprise."
"The UP team proudly presented the Person Tracking demo with the Intel RealSense Robotic Development Kit. The RealSense camera R200 works perfectly with the UP board whether you use it with either Windows or Ubuntu."
Secondly, Microsoft created a robot panda that runs on Windows 10 IoT Core.
"During testing of Windows 10 IoT Core running on Intel’s new chip, Microsoft created a robot panda called “Bamboo” which is able to connect to Microsoft’s Azure and Cognitive Services and gain sentiment analysis and translation abilities."
“You can speak to Bamboo in any language and she can translate into her native English and understand your mood via Twitter,” said Steve Teixeira, general manager of Microsoft’s Windows Partner Application Experience team, in a statement on Sept. 2. “Bamboo can move about and build an understanding of her environment with the compute platform and an Intel RealSense camera.”
