在Windows中如何取消关机/t命令？

shutdown /a将中止操作。

以下是所有的关机参数列表：

Usage: shutdown [/i | /l | /s | /r | /g | /a | /p | /h | /e] [/f]
[/m \computer][/t xxx][/d [p|u:]xx:yy [/c "comment"]]

No args Display help. This is the same as typing /?.
/? Display help. This is the same as not typing any options.
/i Display the graphical user interface (GUI).
           This must be the first option.
/l Log off. This cannot be used with /m or /d options.
/s Shutdown the computer.
/r Shutdown and restart the computer.
/g Shutdown and restart the computer. After the system is
           rebooted, restart any registered applications.
/a Abort a system shutdown.
           This can only be used during the time-out period.
/p Turn off the local computer with no time-out or warning.
           Can be used with /d and /f options.
/h Hibernate the local computer.
           Can be used with the /f option.
/e Document the reason for an unexpected shutdown of a computer.
/m \computer Specify the target computer.
/t xxx Set the time-out period before shutdown to xxx seconds.
           The valid range is 0-315360000 (10 years), with a default of 30.
           If the timeout period is greater than 0, the /f parameter is
           implied.
/c "comment" Comment on the reason for the restart or shutdown.
           Maximum of 512 characters allowed.
/f Force running applications to close without forewarning users.
           The /f parameter is implied when a value greater than 0 is
           specified for the /t parameter.
/d [p|u:]xx:yy Provide the reason for the restart or shutdown.
           p indicates that the restart or shutdown is planned.
           u indicates that the reason is user defined.
           If neither p nor u is specified the restart or shutdown is
           unplanned.
           xx is the major reason number (positive integer less than 256).
           yy is the minor reason number (positive integer less than 65536).

从 shutdown.exe 帮助：

/a - 终止系统关机。

那么，如果你和我一样使用的是XP系统，请不要按 “待命 "或 "重启"，因为当你的电脑完成这个任务后，它就会关闭。根据你的偏好，Ctrl+Alt+Delete，找到进程选项卡，我不太确定，但你应该会看到进程结束 "自己结束"，这就是关机的作用，它结束进程。现在如果你仔细想想，你不需要一个进程来结束其他进程，然后再删除自己吗？应该有一个类似于 "shutdown.exe "的进程，或者如果你要注销的话，则是 "logout.exe"，只要在这些程序结束任何重要的系统进程之前结束这些程序，就可以取消关机。但是，你要准备好了，因为 "由于'shutdown.exe/logoff.exe'的突然停止，Windows无法关闭/注销 "之类的废话。
