Windows comes packed with a range of built-in diagnostic tools that can help you identify and fix a variety of problems, from performance issues to network errors. Knowing how to use these system tools will save you time, reduce frustration, and keep your PC running smoothly. This guide walks through key diagnostic utilities for beginners and offers advanced tips for seasoned users. Whether you’re troubleshooting slow startup, checking hardware health, or ensuring network connectivity, these tools are essential for every Windows user.
Getting Started: What Are Windows Diagnostic Utilities?
Windows diagnostic utilities are built-in programs designed to check your system’s health, fix common issues, and provide useful information about your computer’s status. They include tools for monitoring hardware, managing system resources, and identifying software conflicts.

Where Do I Find System Tools in Windows?
You can access most diagnostic tools by typing their names in the Start Menu search box. For example, type “Task Manager” or “Resource Monitor” to find and open each tool directly.
Task Manager: Your First Line of Defense
What does it do?
Task Manager shows you what’s running on your computer and how your resources (CPU, memory, disk, etc.) are being used.
How to use Task Manager:
1. Press Ctrl + Shift + Esc to open Task Manager.
2. Click the “Processes” tab to see which apps and background processes are consuming resources.
3. To end a problematic process, right-click it and select “End task.”
Practical example:
If your PC feels sluggish, open Task Manager. Check if an app is using too much CPU or memory. Closing unneeded apps can free up resources and improve performance.
Reliability Monitor: Check for System Errors
What does it do?
Reliability Monitor provides a timeline of system events, including crashes, updates, and hardware failures.
How to use Reliability Monitor:
1. Type “Reliability Monitor” in the Start Menu to find and open it (found within the “View reliability history” option).
2. Review the timeline for red X marks—these indicate errors.
3. Click on an error for detailed information and possible solutions.
Practical example:
If Windows crashed recently, Reliability Monitor can help you pinpoint the cause, such as a failing driver or a problematic update.
Windows Memory Diagnostic: Test Your RAM
What does it do?
This tool checks your computer’s memory (RAM) for errors that can cause crashes or instability.
How to use Windows Memory Diagnostic:
1. Type “Windows Memory Diagnostic” in the Start Menu and open the app.
2. Choose “Restart now and check for problems.”
3. Your PC will reboot and run the test. Review the results after logging back in.
Practical example:
If you’re experiencing random program crashes or blue screens, a memory test can quickly tell you if your RAM is failing.

Performance Monitor: In-Depth Resource Analysis
What does it do?
Performance Monitor lets you track detailed system activity, including custom monitoring of CPU, memory, disk, and network usage over time.
How to use Performance Monitor:
1. Press Windows + R, type “perfmon” and press Enter.
2. Explore the “Performance Monitor” section for real-time stats.
3. Use “Data Collector Sets” to create and run your own system performance reports.
Advanced tip:
Set up alerts for specific events, like high disk usage, so you’re notified before a minor issue becomes a major headache.
Event Viewer: Analyze Detailed Log Files
What does it do?
Event Viewer provides logs for application, system, and security events.
How to use Event Viewer:
1. Type “Event Viewer” in the Start Menu.
2. Browse different log categories under “Windows Logs.”
3. Look for warning or error messages to diagnose complex issues.
Advanced tip:
Filter logs by date or keyword to quickly zero in on recurring problems, such as failed hardware or driver conflicts.
Network Diagnostics: Solving Connectivity Problems
What does it do?
Windows includes built-in troubleshooting for network issues.
How to use network diagnostics:
1. Right-click the network icon in the system tray and select “Troubleshoot problems.”
2. Follow the prompts to let Windows identify and suggest fixes for connectivity issues.
Practical example:
If you suddenly can’t access the internet, use this tool first—it can automatically repair common problems like broken network adapters or misconfigured settings.
