问题描述
需要执行某些与安全相关的操作时，Windows在安全桌面"上显示UAC提示.显然在某处有一些API可以创建安全的桌面并在其上创建一个窗口，但是我不知道在哪里可以找到所涉及的机制.我想我可以对UAC机制进行逆向工程，但是我在逆向工程方面并没有那么出色(而且我很确定涉及法律方面的后果...)
Windows displays UAC prompts on the "secure desktop" when certain security-related operations need to be performed. There's obviously some API somewhere that creates the secure desktop and creates a window on it, but I have no idea where I would find out about the mechanisms involved. I guess I could reverse engineer the UAC mechanisms, but I'm not that good at that level of reverse engineering (and I'm pretty sure there's some legal ramifications involved...)
无论如何，我知道当前会话中有一个API可以创建新的桌面，但是我能找到的任何文档中都没有提到安全桌面.出于好奇，我想知道整个安全桌面/UAC提示创建的工作原理.
Anyway, I know there's an API to create new desktops on the current session, but there's no mention of secure desktops in any documentation I can find. Out of curiosity, I'd like to know how the whole secure desktop / UAC prompt creation works.
免责声明:这纯粹是理论上的，我不希望在我的任何代码中部署它.
推荐答案
从系统的角度来看，安全桌面似乎只是具有适当ACL的完全正常的桌面.请注意，CreateDesktop允许您为新桌面指定安全描述符.
It seems likely that, from the point of view of the system, the secure desktop is just a perfectly normal desktop with a suitable ACL. Note that CreateDesktop allows you to specify a security descriptor for the new desktop.
据我所知，安全桌面没有任何特殊行为，因此我认为没有理由假定涉及任何其他API(已记录或未记录).
So far as I know, the secure desktop has no special behaviour, so I see no reason to suppose that any additional API (documented or not) is involved.
