在完成关闭之前，使用WMI命令关闭Windows XP PC需要鼠标/键盘输入

我们使用WMI服务远程关闭办公室中的PC。

这适用于我们的Windows 7系统，但我们发现我们的Windows XP PC在收到远程关机命令后无限期地陷入“关闭”状态。

有趣的是，如果在违规PC的键盘上按下一个键或者鼠标被轻推，PC将继续关闭并在大约10秒内关闭电源。

什么可能导致这种行为？

显然，Windows XP，Vista，7和8都带有一个shutdown.exe用于此类事情（虽然参数/参数在XP之后发生了变化）。在我的Windows 8.1系统上：

C:\Windows\System32>shutdown /?
Usage: shutdown [/i | /l | /s | /r | /g | /a | /p | /h | /e | /o] [/hybrid] [/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         Full shutdown and restart the computer.
/g         Full 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.
/hybrid    Performs a shutdown of the computer and prepares it for fast startup.
           Must be used with /s option.
/e         Document the reason for an unexpected shutdown of a computer.
/o         Go to the advanced boot options menu and restart the computer.
           Must be used with /r option.
/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).

编辑：我只是提到它，因为它可能不会显示相同的行为。至于导致挂起的原因，可能是在这些XP系统上运行的任意数量的程序。我记得看到某些版本的Windows抱怨在关闭之前等待特定程序关闭，但我从未听说过一些键盘/鼠标活动后挂起消失的实例。
