答案 (The Answer)

SuperUser contributor JdeBP has the answer for us:

Your question of course originates from your answer at StackExchange, in particular from kinokijuf’s comment upon the initial revision of your answer.

你从你的回答在课程起源的问题StackExchange ，特别是在你的答案的初始版本kinokijuf的评论。

As kinokijuf said, Windows is not Unix. On Unices and Linux, shutdown is indeed involved in the full shut down process. It is the program that sends regular warning messages to logged-in users and that writes the /run/nologin file to prevent further logging-on a short while before the scheduled shut down time.

正如kinokijuf所说，Windows不是Unix。 在Unices和Linux上，关机确实涉及整个关机过程。 该程序会向登录的用户发送常规警告消息，并写入/ run / nologin文件，以防止在计划的关闭时间之前不久进行进一步的登录。

On Windows NT, this is not the case.

在Windows NT上不是这种情况。

The “shut down” action on the “power button” on the Windows Explorer Start menu, the “shut down” menu option in Task Manager, REBOOT /S in TCC or Take Command, and other application programs that allow you to shut the system down all initiate shut down by directly calling one of two Win32 API calls: InitiateSystemShutdownEx() or ExitWindowsEx(). They do not do things indirectly by running the shut down program. That actually needs more code to do than just calling the Win32 API call. The shut down program, when one is doing a local shut down, calls those same Win32 API calls too.

Windows资源管理器“开始”菜单上“电源按钮”上的“关闭”操作，任务管理器中的“关闭”菜单选项，TCC或Take Command中的REBOOT / S以及其他允许您关闭系统的应用程序通过直接调用以下两个Win32 API调用之一来关闭所有启动器：InitiateSystemShutdownEx()或ExitWindowsEx()。 他们不会通过运行关闭程序间接执行操作。 实际上，这不仅需要调用Win32 API调用，还需要执行更多代码。 关闭程序在进行本地关闭时也会调用相同的Win32 API调用。

It is actually winlogon, csrss, and smss that are the programs that shut down Windows NT. In particular, it is winlogon that does the main work of processing deferred shut down requests.

实际上，winlogon，csrss和smss是关闭Windows NT的程序。 特别是，winlogon负责处理延迟的关闭请求。
