Reset Reliability Monitor In Windows Operating System

Reliability Monitor is an advanced tool that measures hardware and software problems and other changes to your computer. It collects 24 hours of data before it displays any results and calculates the Stability Index that ranges from 1 (the least stable) to 10 (the most stable). You can use the index to help evaluate the reliability of your computer by reviewing the reported application failures, Windows 8 failures, miscellaneous failures, warnings, and other information. Any change you make to your computer or problem that occurs on your computer affects the stability index.


You can tell your Index score (scales from 1 to 10, 10 is the best score) by looking at how the chart line ends in the upper right corner boxed in red below compared to the scale of 10 to 1 on the left upper corner boxed in red below.

In Windows 8, press Windows Key + W, type reliability in the search box, from search results pick View reliability history to access Reliability Monitor.

Now in this article, I’ll tell you the way to reset the Reliability Monitor in case you have fixed the errors or just want to clear the reported data in Reliability Monitor. If Reliability Monitor is not working you may reset it and see if it helps.
