When a spreadsheet becomes very large, opening and processing it requires more memory (RAM). If the system doesn't have sufficient memory, it may fail to load the file properly. Upgrading or increasing the available RAM can resolve performance and loading issues with very large files.
A: Restore points roll back system settings, not individual file content.
C: Defragmentation optimizes disk performance but won't help with memory issues.
D: Network speed has no effect if the file is stored and opened locally.

The correct answer is B. Restarting the print spooler from services, because the problem is isolated to one user and the print job is stuck or failed in the local print queue. This strongly indicates a print spooler service issue on the user's workstation.
According to the Quentin Docter - CompTIA A+ Complete Study Guide, the print spooler manages print jobs sent from applications to printers. If the spooler service hangs or becomes unstable, print jobs may fail even though network connectivity and the printer itself are functioning correctly.
The Travis Everett & Andrew Hutz - All-in-One Exam Guide explains that restarting the print spooler is a standard troubleshooting step when jobs remain in a failed or paused state. This clears the queue and reloads the service without requiring a full system reboot.
The Mike Meyers / Mark Soper Lab Manual reinforces that reinstalling printers should be done only after service-level troubleshooting has failed. Printing from another computer is unnecessary because other users are already printing successfully, confirming the printer and network are operational.
Because the failure is local to the user and visible in the queue, restarting the print spooler service is the most logical and efficient next step, making B the correct answer.

The correct answer is C. Listen to the customer's concerns and acknowledge their frustrations, because effective communication and empathy are critical components of professional help desk interactions- especially when customers are upset.
According to the Quentin Docter - CompTIA A+ Complete Study Guide, technicians should always demonstrate active listening, empathy, and professionalism. Acknowledging a user's frustration helps de- escalate tense situations and builds trust.
The Travis Everett & Andrew Hutz - All-in-One Exam Guide emphasizes that users who feel unheard are less cooperative and more dissatisfied. Before troubleshooting or escalation, technicians should validate the customer's experience and reassure them that the issue will be addressed.
The Mike Meyers / Mark Soper Lab Manual reinforces that blaming previous technicians or immediately escalating without communication can worsen the situation. Asking technical questions too early may come across as dismissive.
Because the goal is to communicate professionally and effectively, the technician should first listen and acknowledge the user's frustration, making C the correct answer.

Event Viewer is the best tool to analyze the root cause of service failures in Windows. It provides detailed logs from system processes, including errors, warnings, and crash reports related to services and applications.
When a service starts and stops unexpectedly, Event Viewer will often record the cause, such as dependency failures or access violations.
B: Task Manager shows active processes but doesn't retain logs or causes of failure.
C: Internet Options is used for configuring browser settings, not troubleshooting services.
D: Process Explorer is powerful but more suited for live monitoring and detailed process trees, not post- failure log analysis.
