Solution 1

You will probably need to implement OnShutdown()[^] method, or similar.

Does Shutdown like power off plugin

Sorry, but I don't understand what you mean.

I think the OP wants to know if they can track the situation where there is sudden power loss of some kind as opposed to a controlled reboot/shutdown.

Thanks, got the idea.

Marcus's suggestion would lead me to OnPowerEvent notification.

Solution 2

Create a windows service and log the information you require to an external database on a server machine.

If I understand your question correctly, I think you want to be able to trace the time at which a sudden power loss, hard shut down occurs on the system whereby there won't be an entry in the system event logs. The only suggestion I would have is that you use Mehdi's suggestion to create a simple service that writes something every minute or so to an external database by which you will then be accurate to within a minute if such an event occurs.
