How to use Windows Reliability Monitor to check Windows health

If your Windows computer suddenly shuts down or applications keep crashing, you can use the Windows Reliability Monitor tool. This is a testing tool, a diagnostic tool to see if there are any problems with your Windows computer. The tool provides a user-friendly interface to help identify and fix system problems, Windows update problems, hardware and driver problems. Here is a guide to using Windows Reliability Monitor to check Windows.

How to use Windows Reliability Monitor

Step 1:

You enter the keyword reliability in the search bar and then click on the tool displayed above to open.

Step 2:

Then you will see the Windows Reliability Monitor tool interface as shown below.

You can select a day or week in the upper left corner of the chart to view data. Or users can view data for a month available in the chart, or other information by clicking View all problem reports .

Step 3:

In the Windows Reliability Monitor graph, the blue line represents the Reliability Scale, which ranges from 10 being the most reliable to 1 being the least reliable.

On the right side of the chart, you will see labels that include:

1. Application Failures
2. Windows Failures
3. Miscellaneous Failures
4. Warnings
5. Information

There are also icons that display different content:

1. Red circle: phenomenon occurs that affects system reliability.
2. Yellow triangle: indicates warning events that do not directly affect system stability. But you should pay attention to these items to avoid problems.
3. The blue circles with the letter "i" represent information events. They will provide data about various successful updates.

Step 4:

Now you click on any day to see information about the status of Windows. For example, on June 9, 3 icons are displayed.

Red circles are important events about some system-affecting errors and warnings about Windows Update.

Step 5:

You click on an error message and see detailed information about that error on your computer.
