220-1102 Practice Question: That their Windows 10 PC is running slowly after…
A user reports that their Windows 10 PC is running slowly after they installed a new program. You need to identify which service or startup program is consuming the most CPU resources to troubleshoot the issue. Which administrative tool should you use?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Task Manager
Task Manager provides real-time performance monitoring, including CPU usage per process. This makes it the ideal tool for quickly identifying resource hogs. Other tools like Event Viewer or Services.msc are for different purposes.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Event Viewer
Why it's wrong here
Event Viewer is a Windows utility primarily used for logging and reviewing system, security, application, and setup events. While it records critical errors or warnings that might indirectly relate to a process consuming excessive resources (e.g., an application crash), it does not provide a live, granular view of CPU utilization by individual processes. Its core function is historical logging and diagnostics, not real-time performance monitoring for resource consumption.
- ✓
Task Manager
Why this is correct
Task Manager is the definitive Windows utility for real-time system monitoring and process management, making it ideal for diagnosing high CPU usage. Specifically, its "Processes" or "Details" tab provides a dynamic, sortable list of all running applications and background processes, clearly displaying their current CPU, memory, disk, and network utilization. This direct visibility allows a technician to quickly identify which specific process is causing excessive CPU usage and impacting overall system performance.
- ✗
Services.msc
Why it's wrong here
Services.msc, or the Services console, is designed for managing background Windows services, allowing users to configure their startup type, start, stop, or disable them. While a misbehaving service could indeed consume excessive CPU resources, this utility only shows the service's operational status (e.g., running, stopped) and configuration details, not its current resource consumption. To determine a service's CPU usage, one would typically need to identify its associated process within Task Manager.
- ✗
Performance Monitor
Why it's wrong here
Performance Monitor, part of the Reliability and Performance Monitor suite, is a powerful and highly configurable tool for collecting and viewing extensive performance data over time using various system counters. While it is capable of displaying real-time CPU usage for processes, its interface is more complex and geared towards detailed analysis, logging, and custom reporting rather than a quick, immediate identification of a single high-CPU process. For a rapid assessment of current CPU usage, Task Manager offers a significantly more direct and user-friendly experience.
