服务（Service）对于大家来说一定不会陌生，它是Windows 操作系统重要的组成部分。我们可以把服务想像成一种特殊的应用程序，它随系统的“开启～关闭”而“开始～停止”其工作内容，在这期间无需任何用户参与。Windows 服务在后台执行着各种各样任务，支持着我们日常的桌面操作。有时候可能需要服务与用户进行信息或界面交互操作，这种方式在XP 时代是没有问题的，但自从Vista 开始你会发现这种方式似乎已不起作用。
现在有个需求需要服务程序弹框提示和启动包含复杂UI的桌面程序，"穿透Session 0 隔离"这篇文章已经写得很好了，看了之后非常有帮助，但是在最后启动了cmd之后发现就只能启动cmd，启动其他类型的程序都会报错。仔细看了评论发现还是没有解决，只是照着抄了一遍，发现不仔细看还是不是自己的东西（知识）啊。

最后修改了一下程序，解决了问题。跟原博主李敬然写的稍微有点区别。我的是抄的msdn的代码。总之就是 CreateProcessAsUser 函数的申明和调用有些区别。
