关闭事件跟踪程序（Shutdown Event Tracker，缩写为 SET）是 [[Microsoft Windows 通述|Microsoft Windows]] 中的一项功能，用于跟踪操作系统的关闭活动。如果激活，它会在调用关机选项时询问用户计算机即将关闭的原因。它还会询问用户计算机在不正确关闭或[[蓝屏死机|停止错误]]后意外停止的原因。

== 历史 ==
它在 [[Windows 2000 Build 1946.1|Windows 2000 Build 1946]] 中作为“关闭原因”引入，在单击“关闭”提示符上的“确定”后出现其提示。它已集成到关机提示符中，并在 [[Windows XP Build 2223]] 中成为关闭事件跟踪程序，但在 [[Windows Server 2003 Build 2267.1.idx01.000910-1316|Windows Server 2003 Build 2267]] 之前，它默认未为 Advanced Server/Enterprise Server SKU 激活。

从 [[Windows 8]] 开始，关闭事件跟踪程序在“开始”菜单或登录屏幕中显示为浮出控件。它后来在 Windows 10 及更高版本中删除。

==How to enable==
Shutdown Event Tracker is enabled by default only for server releases, but it also can be enabled for client releases by using the following registry edit:
<syntaxhighlight lang="registry">
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Reliability]
"ShutdownReasonOn"=dword:00000001
"ShutdownReasonUI"=dword:00000001
</syntaxhighlight>

Alternatively, on [[Windows XP]] and later, the group policy "Display Shutdown Event Tracker" in "Computer Configuration → Administrative Templates → System" can be set to Enabled.
