Wevtutil is a command-line utility in Windows that allows users to manage event logs and event log files. It is a powerful tool for system administrators and engineers who need to interact with the Windows Event Log service, which is crucial for monitoring and troubleshooting system activities.

Examples:

1. Listing Event Logs:

   To list all the event logs on your system, you can use the following command:

   wevtutil el

   This command will output a list of all available event logs, such as Application, Security, System, etc.

2. Exporting Event Logs:

   If you need to export an event log to a file for analysis or archiving, use the following command:

   wevtutil epl Application C:\Logs\ApplicationLog.evtx

   This command exports the Application event log to a file named ApplicationLog.evtx located in the C:\Logs directory.

3. Querying Event Logs:

   To query specific events from an event log, you can use the qe command with an XPath query. For example, to find all error events in the System log, use:

   wevtutil qe System /q:"*[System[(Level=2)]]"

   This command queries the System log for events with a level of 2, which indicates errors.

4. Clearing Event Logs:

   To clear an event log, use the cl command. For example, to clear the Security event log, run:

   wevtutil cl Security

   This command clears all events from the Security log.

5. Retrieving Event Log Information:

   To get detailed information about a specific event log, such as its size and number of records, use:

   wevtutil gli Application

   This command provides information about the Application log.
