我可以从Windows 7中的命令提示符启动Windows服务，而不必以管理员身份运行命令窗口，如下所示：
sc start myservice
但是，如果我在Windows 10上执行相同的操作，它将无法启动服务，并返回“拒绝访问”错误。如果我以管理员身份启动命令窗口，它确实可以正常运行。
我真正想要的是从C ++代码启动服务，但是Windows 10上的管理特权正在妨碍我。 Windows 7和10之间似乎有明显的区别，但是OpenService()文档根本没有讨论它！
现在，这是一个愚蠢的问题，询问我们是否可以解决此安全问题，但是是否可以通过设置某些安全属性来解决它？
在下面的代码中，OpenService()失败，错误代码5，因为它要求SERVICE_START权限：
