The EventLog Service

  • Dependency: The entire event logging system relies on the Windows Event Log service (service name: eventlog). This service is responsible for managing log files, receiving events from providers, and allowing tools like Event Viewer to access the logs.

  • Critical Status: If the eventlog service is stopped, no new events will be recorded, and Event Viewer (and other log analysis tools) will be unable to function. Finding this service stopped during a screenshare is extremely suspicious and strongly suggests tampering or a significant system issue.

  • Checking Status: The service status can be verified using an administrative Command Prompt or PowerShell: sc query eventlog. The expected state is RUNNING.
