Shutdown Event Tracker

Shutdown Event Tracker is a functionality in Microsoft Windows, which tracks the shutdown activity of a computer. If activated, it asks the user for a reason why the computer is about to be shut down any time the Shut down option is invoked. It also asks the user for a reason why the computer stopped unexpectedly after a improper shutdown or a Stop error.

History
It was introduced in Windows 2000 build 1946 as "Shut Down Reason", where its prompt appears after clicking OK on the Shut Down prompt. It was integrated into the Shut Down prompt and became the Shutdown Event Tracker in Windows XP build 2223, but it was not activated by default for the Advanced Server/Enterprise Server SKU until Windows Server 2003 build 2267.

Since Windows 8, the Shutdown Event Tracker appears as a flyout in the Start menu or the login screen.

Alternatively, on Windows XP and later, the group policy "Display Shutdown Event Tracker" in  can be set to Enabled.
