The Event Viewer on Windows 11 is an application that collects system and app event logs on a friendly interface that you can use to monitor and troubleshoot problems. Also, it can come in handy to track the performance of your computer.
Whenever the computer runs into an error, security concern, or any other issue, the Event Viewer should be the first place to check to start troubleshooting the problem since the tool records virtually every app crash, hardware failure, driver problem, and security issue into event logs.
