命令行 windows 是否重启正常退出 运行 app
Does command line windows restart gracefully exit running app
平台：Windows2008服务器
运行 遇到一个问题，我用 pyinstaller 生成的单文件 exe 不会清除其关联的临时文件夹。阅读此 http://pythonhosted.org/PyInstaller/ 并发现如果 exe 没有正常关闭它不会删除其关联的临时文件夹。在此之后，我与设置 exe 的 IT 人员进行了交谈，并被告知该应用程序在系统启动时启动，并且每天晚上都会重新启动系统。
我尝试了解系统在 windows 重新启动是否会正常退出 运行 应用程序，但找不到任何相关信息。
有谁知道 windows 是否正常退出 运行 应用程序并安排系统重启？

是的，确实如此，但是 implementation slightly differs between XP\Vista. You can also change shutdown timer and auto-close behaviour: How to Specify WaitToKillAppTimeout to Speed Up Shut Down Time in Windows。
在 Windows 经验中：
In Windows XP, each running application is sent the WM_QUERYENDSESSION
message at shutdown. Applications can return TRUE to indicate that
they can be closed, or FALSE to indicate that they should not be
closed (e.g., because doing so would cause the user to lose data or
destroy a CD being burned). If an application returns FALSE, in most
cases, shutdown will be cancelled (and the application that cancelled
shutdown is sent WM_ENDSESSION with wParam == FALSE).
Applications can also delay responding to WM_QUERYENDSESSION in order
to display UI asking what the user would like to do. For example, when
Notepad has unsaved data and displays a "Would you like to save your
data?" dialog during shutdown, this is what it is doing. By default,
applications can delay responding to WM_QUERYENDSESSION for up to 5
seconds. After 5 seconds, Windows XP will display a dialog that
indicates that the application is not responding and allows the user
to terminate it. Until the user responds to this dialog, applications
can block WM_QUERYENDSESSION (and, consequently, shutdown)
indefinitely.
在 WindowsVista
Ability for users to forcefully shut down
In Windows XP, the UI for
blocking applications allows users to either cancel shutdown or
terminate the blocking application. If subsequent applications also
block shutdown, the system displays identical UI for each blocking
application. This is frustrating for many users, who, when shutting
down, "just want" their computers to turn off. Windows Vista will
solve this by allowing users to terminate the blocking application and
make shutdown "forceful." In a forceful shutdown, Windows will send
applications WM_QUERYENDSESSION with the ENDSESSION_CRITICAL flag. If
an application responds FALSE, Windows will continue shutdown instead
of canceling it, and will send the application WM_ENDSESSION. If an
application times out responding to WM_QUERYENDSESSION or
WM_ENDSESSION, Windows will terminate it.
Silent shutdown cancellations will no longer be allowed
In Windows XP,
applications are allowed to veto WM_QUERYENDSESSION without displaying
any UI indicating why they need to cancel shutdown. These "silent
shutdown failures" are highly frustrating to users, who often take a
minute or two to realize that shutdown has failed because no UI was
displayed. Windows Vista will eliminate this possibility by displaying
UI even if an application vetoes WM_QUERYENDSESSION.
Certain types of applications will no longer be allowed to block
shutdown. At shutdown, Windows Vista will check whether each running
application is not responding (an application is defined as not
responding if it has not responded to any of its window messages in
the last 5 seconds), and, if so, automatically terminate it.
Windows Vista will also not allow console applications or applications
that have no visible top-level windows to block shutdown. In most
cases, such applications are less important to users at shutdown than
applications that do have visible top-level windows. If an application
without a visible top-level window blocks shutdown by vetoing
WM_QUERYENDSESSION, or takes over 5 seconds to respond to
WM_QUERYENDSESSION or WM_ENDSESSION, Windows will automatically
terminate it.
However, if an application with no visible top-level windows uses the
new API to proactively indicate that it needs to block shutdown,
Windows Vista will not automatically terminate it, and will instead
treat it like an application that does have a visible top-level
window.
