I've worked with the NT kernel source. So no way in hell. The stack is too deep and too opaque for generic embedded stuff IMHO.
Plus with no source, no support contract, if something blows up, even with a checked build (which appears not to be available), debug symbols, windbg running remotely, most of it is just a bucket of hell waiting for you. GDB remote debug is marvelous in comparison. Hell even most of the build in kernel debugging stuff in linux is pretty nice. Oh it blew, backtrace, ahhhhhhhhhhhhh I see.
