Checking diagnostic reports during troubleshooting is essential primarily because they provide critical insights into application errors. Diagnostic reports compile detailed information about the state of the operating system, applications, and hardware at the time of an issue. This information can pinpoint specific problems, such as crashes or bugs, and help determine the root cause of an application's malfunction.

For instance, when troubleshooting an application that has unexpectedly crashed, the diagnostic report will often contain logs of recent activities, error messages, and stack traces that clarify what went wrong. This targeted data is invaluable for users and support technicians alike to streamline the troubleshooting process and devise effective solutions.

While verifying user settings, identifying system resource usage, and finding installation logs are also important aspects of troubleshooting, the direct link between diagnostic reports and application errors makes the examination of these reports a critical initial step in resolving issues efficiently.
