> Currently, in command executor, we use different code path for posix and windows:
> {noformat}
> #ifndef __WINDOWS__
>     pid = launchTaskPosix(
>         command,
>         launcherDir,
>         user,
>         rootfs,
>         sandboxDirectory,
>         workingDirectory);
> #else
>     // A Windows process is started using the `CREATE_SUSPENDED` flag
>     // and is part of a job object. While the process handle is kept
>     // open the reap function will work.
>     PROCESS_INFORMATION processInformation = launchTaskWindows(
>         command,
>         rootfs);
>     pid = processInformation.dwProcessId;
>     ::ResumeThread(processInformation.hThread);
>     CloseHandle(processInformation.hThread);
>     processHandle = processInformation.hProcess;
> #endif
> {noformat}
> During a recent refactor (MESOS-5753), for the posix path, command executor reused `mesos-containerizer launch` helper to launch user tasks.
> If we were to be able to support job_object in Subprocess, we can get rid of this divergence in command executor. This also allow us to support custom executors on Windows.
