Aiming at the problems of interoperability between Linux and Windows in desktop domain, network domain and embedded domain, solutions are systematically illustrated in this paper. In desktop domain, the two operating systems can mutually run programs, can mutually deal with data files, and can mutually access file systems. In network domain, the two systems can support the shared operations of resources and services between them under the network environment by adopting the same network protocols. In embedded domain, by adopting the technologies such as virtualization and code refactoring, the two systems can mutually support the cross development of application softwares in local system, mutually support the transplanting of application softwares to local system.
