Windows Event Viewer is a utility that shows users logs of events generated by the Windows operating system, and applications/services running on Windows.

The Windows Event Viewer displays events that have been logged, along with each event's severity and several other useful details. Event Viewer runs through Microsoft Management Console. Custom views of events can be created, saved, and exported, allowing users to filter the event log to specific event types, specific applications, specific time ranges, etc.
