Wind River (Subsidiary of Intel) has a large foothold in the IoT market with their VxWorks and WR Linux OSs that play in the embedded/MCU market. Also see their free new open source OS, Rocket, which is being developed as the "Zephyr Project" in collaboration with the Linux Foundation.
WR is aggressively building out its Helix Cloud platform. Silicon is useless without the services/app dev/data management backend. If WR can migrate OS users up to Helix Cloud they can (somewhat) offset losses on Intel hardware and giving the newer OSs away for free.
With regards to OS for microcontrollers, ARM's mbed has far better low-power,security and ecosystem story.
And as far as Linux OS's - nobody will buy an OS that can't be ported to ARM and be done so reasonably, so i'm not sure Wind River helps Intel that much in selling chips.
