Windows Event Viewer
The eventvwr command opens the Windows Event Viewer, a powerful tool for viewing and analyzing event logs. Event Viewer displays detailed information about significant events on your computer, such as program crashes, security warnings, system errors, and application activity.
Think of Event Viewer as your system's flight recorder. Every important event—from successful logins to critical system failures—is logged here. It's essential for troubleshooting issues, monitoring security, auditing system changes, and understanding what happened before, during, and after problems occur.
