Windows 10: Windows 10 shut down in the night, Event Log not helpful, can't determine the cause

Hello! I'm on Windows 10. Yesterday, at some point in the night, Windows shut down on its own. This was very annoying, as my power plan is set to never even put the PC to sleep as long as it's plugged in, and the laptop has been plugged in all night long - I thought this would be enough.So I turned to the Event Viewer, and found something weird.The last relevant events from earlier this morning are these:Information 13/05/2025 04:50:31 Kernel-Power 42 64> The system is entering sleep.Sleep Reason: System Idle> Information 13/05/2025 04:52:53 Kernel-Po

method to determine exactly what caused a particular update?

Two suggested articles from Microsoft....

• Fix Windows Update errors
• Troubleshoot problems updating Windows 10

Whether you find the exact cause will determine the level of troubleshooting you go through.

 

How do I review logs to determine when and why computer is shutting down?

Hi justinCTU,

I am Dave, I will help you with this.

Click your Start Button, then just type event and from the resulting list, open the Event Viewer.

On the left in the Event Viewer, go to Windows logs - System, in there you should be able to trace if something is wrong and causing your PC to shut down.

 

You are about to be logged off - Windows will shut down in 1 minute

Hi,

Thank you for contacting Microsoft Community.

I suggest you to check whether the automatic restart option is disabled or not as below.

• Press “Windows+X” and go to “Control Panel”.
• Click on “System and Security” and click on “System”.
• On the left hand side click on “Advanced system settings”.
• Click on “Advanced” tab, then under “Startup and Recovery” click on “Settings”.
• Under “System Failure” uncheck the option “Automatically Restart”.
• Then click on “ok” and check whether the issue persist or not.

Also, I suggest you to check whether any task has been schedule for automatic restart as below.

• In the search box type as “Task Scheduler”.
• Under “Task Scheduler summary” you can find any task has been created or not.
• If any task has been created then I suggest you to remove it and check if the issue persist or not.

To determine what is causing the issue, I suggest you to check the event logs in the event viewer logs to know more about the issue.

Try the following steps to access Event Viewer:

• Press 'Windows key + R' simultaneously on your keyboard to bring the run dialog box.
• Type ‘eventvwr’ (without quotes) and press ‘OK’.
• Expand ‘Windows Logs’ on the left pane and look for the error logs under Application and System.
• Copy the information and post it here so that we can analyze it.
