Answer: B - The Event Viewer can be useful in identifying internal errors and bottlenecks occurring with the Windows 7 OS.

Key Takeaway: The Event Viewer logs errors and warnings occurring with the System, Application, and Security areas of the OS. This is a helpful place to go when you are attempting to solve an OS issue, (for instance, why you continually get an error on startup, or why a program closes as soon as it opens). MSCONFIG is useful for troubleshooting errors found in the event viewer, and MSINFO32 provides useful information about your computer hardware and use. CHKSDSK is useful for fixing hard drive errors.
