IIRC the NT kernel can run multiple kernels-or-something side by side. It could probably be used to co-run Linux kind of like CoLinux does. IIRC also, MS can use the Windows HyperV infrastructure to run the Linux kernel too, like they do on Xbox One to segregate games "Exclusive" OS from apps "Shared" OS. In that sense it won't be user mode either like user-mode linux is. My bet is on the latter. https://en.wikipedia.org/wiki/Architecture_of_Windows_NT https://en.wikipedia.org/wiki/Architecture_of_Windows_NT https://en.wikipedia.org/wiki/Xbox_One_system_software https://en.wikipedia.org/wiki/Xbox_One_system_software https://en.wikipedia.org/wiki/Cooperative_Linux https://en.wikipedia.org/wiki/Cooperative_Linux https://en.wikipedia.org/wiki/User-mode_Linux https://en.wikipedia.org/wiki/User-mode_Linux
