Most users never realize Windows has a built‑in diagnostic tool that visually maps every crash, warning, and system update: Reliability Monitor.

Unlike Event Viewer (which can feel overwhelming), Reliability Monitor shows issues on a clean timeline with clear explanations.

You can pinpoint exactly when an issue happened, what caused it, and which app or update triggered the failure.

It’s incredibly useful for diagnosing recurring crashes, verifying whether updates caused problems, and giving IT support teams precise, actionable information.

✅ Benefits

• Quickly identify the root cause of app crashes
• Understand patterns (e.g., issues after a specific update)
• Save troubleshooting time by eliminating guesswork
• Generate reports for IT or vendors
• More user‑friendly than Event Viewer

🛠️ Procedure

1. Press Windows Key → type “Reliability Monitor” → open “View reliability history.”

2. Review the timeline for red X (Critical events), yellow triangles (Warnings), or blue info icons (Updates/Installs).

3. Click any event to see details such as:

• Faulting application
• Error type
• Windows update history
• Related system changes

📎 Notes

You can export reliability history as an XML file for IT teams.

Extremely useful before reinstalling apps—check the cause first.
