System Stability Monitor in Windows 10 and Windows 11: How to Use and Analyze

Windows has built-in tools for monitoring system stability and troubleshooting. One of these tools is the System Stability Monitor (or Reliability Monitor), which tracks errors and warnings that occur during use. In this guide, we’ll explore how to use the Stability Monitor in Windows 10 and Windows 11 and what insights it can provide.

What is the System Stability Monitor?

The Stability Monitor is a Windows feature that allows users to analyze system stability and identify the causes of failures. It displays system event data, such as application errors, hardware failures, failed updates, and security warnings. Based on this data, the Monitor generates a stability score, helping users quickly gauge how stable their system is.

How to Open the Stability Monitor in Windows 10 and Windows 11

Launching the Stability Monitor is straightforward, and the process is the same for both Windows versions:

  1. Press Win + S and type "Reliability Monitor" or "View reliability history."
  2. Select View reliability history from the list.
  3. Alternatively, press Win + R, enter perfmon /rel, and press Enter.

Interface and Key Functions of the Stability Monitor

The Stability Monitor interface displays a chart with stability scores, where each point represents a day and shows the system stability level on a scale from 1 to 10. Events are divided into several categories:

  • Critical Errors: indicate application or system crashes that need attention.
  • Warnings: highlight potential issues, such as outdated drivers or performance issues.
  • Informational Messages: show successful updates or application installations.

Analyzing Data and Troubleshooting

To analyze your system’s stability, select any day on the chart. A detailed list of events from that day will appear on the right side of the window. Pay attention to the following points:

  • Applications that crashed: frequent crashes of a specific app may indicate the need to update or reinstall it.
  • Windows errors: system errors may signal hardware issues, such as with the hard drive or memory.
  • Update warnings: monitor information about driver and system updates, as they often fix identified issues.

Practical Tips to Improve System Stability

To improve system stability and reduce errors, follow these recommendations:

  1. Regular updates: keep Windows, drivers, and software up to date.
  2. Virus scans: use antivirus software to scan for malware that could affect stability.
  3. Registry and disk cleanup: regularly remove temporary files and fix registry errors.
  4. Hardware diagnostics: check your hard drive, memory, and other components for failures using built-in Windows tools or third-party software.
