Windows 10 shutdown and restart logsSource: Windows Central

On Windows 10, the Event Log system tracks everything that happens, including when and why the computer restarts or shuts down correctly or due to a problem.

Although you would not typically think about reviewing this information as long as Windows 10 starts up again correctly, sometimes, you may need to know these details to determine if there is an issue that needs attention. Or to understand if Windows Update suddenly rebooted the system to apply a new update, or the device lost power unexpectedly.

Regardless of the reason, Windows 10 includes different ways to check the date, time, and reason why the system shut down or restarted unexpectedly using the Event Viewer or querying the event logs with PowerShell and Command Prompt.

  5. In the "All Event ID" textbox, include the following ID numbers separated using a comma:

    • 41 — The device did not restart correctly using a clean shutdown first. This event could be caused if the computer stopped responding, crashed, or lost power unexpectedly.
    • 1074 — This event is triggered when the user initiates a manual shutdown or restart. Or when the system restarts automatically to apply updates, for example. If you were using the shutdown command with a custom message, the information would be recorded in the "Comment" section.
    • 6006 — This event is logged when the Event Log system has been stopped by during a good shutdown. This error usually happens after error 1074.
    • 6005 — This event is logged when the Event Log system started, which can indicate when the computer was booted.
    • 6008 — Indicates that the previous system shutdown was unexpected. This error will usually happen after error 41.

    Quick tip: You can use the down and up keyboard arrows to browse between events. As you move between the logs, the details will appear at the bottom of the screen, in the "General" tab.

Once you complete the steps, you will know when and the possible reason (such as Blue Screen of Death, crashed, unexpected power lost, etc.), which may have caused the reboot or shutdown of the computer.

Unless you can link these logs to another system component error log, it would be difficult to identify what exactly forced the device to unexpected. However, these events will help to under what happens and where to continue looking.
