How to View Reliability History in Windows 10
Reliability Monitor is an advanced tool that provides a system stability overview and details about events that impact reliability. It calculates the Stability Index shown in the System Stability Chart over the lifetime of the system.
Based on data collected over the lifetime of the system, each date in the System Stability Chart includes a graph point showing that day's System Stability Index rating. The System Stability Index is a number from 1 (least stable) to 10 (most stable) and is a weighted measurement derived from the number of specified failures seen over a rolling historical period. Reliability Events in the System Stability Report describe the specific failures.
- Recent failures are weighted more heavily than past failures, allowing an improvement over time to be reflected in an ascending System Stability Index once a reliability issue has been resolved.
- Days when the system is powered off or in a sleep state are not used when calculating the System Stability Index.
- If there is not enough data to calculate a steady System Stability Index, the graphed line will be dotted. When enough data has been recorded to generate a steady System Stability Index, the graphed line will be solid.
- If there are any significant changes to the system time, an Information icon will appear on the graph for each day on which the system time was adjusted.
Reliability Monitor maintains up to a year of history for system stability and reliability events. The System Stability Chart displays a rolling graph organized by date.
The top half of the System Stability Chart displays a graph of the Stability Index. In the lower half of the chart, five rows track Reliability Events that either contribute to the stability measurement for the system or provide related information about software installation and removal. When one or more Reliability Events of each type are detected, an icon appears in the column for that date.
- For Software Installs and Uninstalls, an Information icon indicates a successful event of that type occurred, or a Warning icon indicates a failure of that type occurred.
- For all other Reliability Event types, an Error icon indicates a failure of that type occurred.
This tutorial will show you how to view reliability history in Windows 10 to review hardware and software problems that have impacted your system.
Here's How:
1. Open the Control Panel (icon view), and click/tap on the Security and Maintenance icon.
2. Click/tap on the chevron to the right of Maintenance to expand it open, and click/tap on the View reliability history link (perfmon.exe /rel). (see screenshot below)
3. Reliability Monitor (perfmon.exe /rel) will now generate a problems report for a moment. (see screenshot below)
4. Click/tap on an available Days, Weeks, Month, or Year option at the top left of the System Stability Chart (top section) for how you want to view details by. (see screenshots below)
5. To view Reliability details (bottom section) for a specific date, click/tap on the column for that date in the System Stability Chart. You can use the scroll buttons at the left and right sides of the System Stability Chart to find dates outside the visible range.
6. To view more specific details about a problem listed in the Source column in Reliability details (bottom section), you can click/tap on the View technical details link in the Action column for the problem.
7. You can also click/tap on the links below at the bottom of Reliability Monitor if wanted.
- Save reliability history - Saves reliability history as an .xml file to a location you select.
- View all problem reports - To view problems reports that can be reported to Microsoft.
- Check for solutions to all problems - To check for solutions from Microsoft to all problems.
That's it,
