Windows 11 tracks every single software crash, failed update, and hardware fault that occurs on your PC. However, these logs are buried in a tool called the “Event Viewer,” which is so complex and filled with millions of harmless “Information” events that it is practically useless for normal users.
Thankfully, Windows includes a hidden, highly visual dashboard that extracts the most severe errors from the Event Viewer and plots them on a chronological timeline graph. This tool allows you to instantly see a visual representation of your computer’s health over the past month.
How to Safely Extract the Windows 11 Reliability History
You must launch the hidden Reliability Monitor via the legacy Control Panel interface.
- Click the Start button.
- Type reliability into the search bar.
- The top result should say View reliability history (it will have a blue flag icon next to it). Click it.
- A new window will open, and Windows will take a few seconds to extract and parse the massive database of system events.
- You will now see a chronological graph spanning the last few weeks.
Look at the graph. A red ‘X’ indicates a critical software crash or hardware failure. A yellow triangle indicates a warning (like a failed background update). A blue ‘i’ indicates an informational event (like a successful software installation).
Click on any specific day on the graph that contains a red ‘X’. In the bottom half of the window, Windows will extract the exact name of the application that crashed on that specific day (e.g., “Adobe Photoshop – Stopped working”). You can double-click the event to see exactly what `.dll` file caused the crash, allowing you to instantly identify which software is making your system unstable without ever digging through the complex Event Viewer.
