64位Windows创建64位进程逆向分析（总目录）

在上一篇文章中，我们介绍了CreateProcess在3环的整个流程。在其中特别提到，当操作系统由3环切换到0环，是由NtCreateUserProcess完成所有关键工作的。
    在这篇文章中，我们将会介绍0环函数NtCreateUserProcess的整体流程。

准备工作
    我们分析64位的Windows 7发现，其3环切换0环所用的特权指令是syscall(而不是sysenter)，不过，他们两者的区别主要只在兼容模式是否有效上，与我们分析CreateProcess关系不大。不过，0环3环的切换，是既重要又基础的概念，对于还没概念的朋友，可以先查阅下Intel手册或者相关书籍。

    NtCreateUserProcess是一个复杂的函数，如果想在成千上万行的汇编代码中不迷失自己的目标，就要把握好它的核心，在此，我们提前强调三个结构体：
