Check your System Stability Index


On the internet you can find lots of information about the Windows Experience Index. You can find a lot of guides presenting this feature, how it works and how to increase your system ratings. Unfortunately, another similar feature has passed almost unnoticed. It is called the System Stability Index and it allows users to evaluate the stability of their systems and to make informed decisions about how to troubleshoot. 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.

In this article we will show you how to access the System Stability Index of your Windows Vista PC and how to access the information you need regarding the failures that might take place.

The System Stability Index is shown by the Reliability and Performance Monitor. To find it, go to Control Panel -> System and Maintanance -> Administrative Tools. You can also use the search box from the Start Menu or the Control Panel to get there faster.

Administrative Tools

In the Reliability and Performance Monitor window, go to Reliability and Performance -> Monitoring Tools -> Reliability Monitor. You will see a graph with dates, symbols and ratings. You can select any day from the graph by clicking on its column and the Reliability Monitor will show you the System Stability Index for that day together with additional information, in case any important system events took place.

To view all available historical data, click the drop-down date menu and click Select all. If more than 30 days of data are available, you can also use the scroll bar at the bottom of the System Stability Chart to browse dates outside the visible range.

Reliability and Performance Monitor

The System Stability Index is shown in the upper right part, as shown in the screenshot above. The additional information is presented below the graph and has the following structure:

  • Software (Un)Installs - shows information regarding software installations and removals including operating system components, Windows updates and drivers;
  • Application Failures - all the application failures, including the termination of a non-responding application or an application that has stopped working, are tracked and listed in this category.
  • Hardware Failures - shows information about disk and memory failures
  • Windows Failures - operating system and boot failures are tracked and listed in this category
  • Miscellaneous Failures - in this category are listed failures that impact stability and do not fall under the previous categories, including unexpected operating system shutdowns.

how do you make your system

how do you make your system stability rate go higher?

Fix your problems

By fixing the stability problems you have. That can mean updating drivers, optimizing settings, uninstalling applications that are not very compatible with Windows Vista, etc...

opps mines at 3.15 whats

opps mines at 3.15 whats yours?

thats why i love xp

thats why i love xp ......... trojans, virus's, worms, spyware, and all.

even with ALL that... you could still count on XP working

That is a fake value 9.59 isn't it?

mine never went over 7.39 currently it is 4.38 because Vista tends to be unresponsive all the time. So either you tweaked this or you do not use your PC.

2.37 Was my lowest....

2.37 Was my lowest.... damn... but even right out of the gate I had 6.13
but had a max of 9.67

But it's true that it happens because of unresponsiveness... Installed Adobe Master Collections CS3 and it's been hovering around 9.0 but it's dropped 6.80 because of the programs freezing when closing them...

No Reliability snap-in or Stability score

Strange. I have no stability score in the corner of my window at all. In the both Performance Monitor mmc and the Computer Management mmc there is no Reliability Monitor under Monitoring Tools. Instead, under either More Actions or View it offers the option to "View system reliability..." which opens the Reliability Monitor in a new Window, but with no Stability score. The events are all logged and the graph is there, just no score.

I have installed all the latest updates and hotfixes to Win7, so maybe they changed it?

Anyway, it's nice to finally find a log of install/uninstalls on my system. I looked all over the Internet for this information a while ago but found no answers. Very cool.

Mine peaked at 10.00

It just dips whenever something goes wrong, and then jump back up when nothing does. But I have serious dips from my own applications crashing, so mine is a little unfair. My worst was 3.32. It recently dipped to 4.78 due to JavaScript apps I'm making that are crashing or being shut down since they aren't finished computing. Took only two weeks to rise back up to 7.30 though. Not sure how this is useful.... to find bad apps and uninstall them, I guess?

9 down to 8

Mines 9 down to 8. My stablity has been rather good. However i've been running games above my spec and badly playing with swapping my graphics card so I'm down to 8 now. The better the tech, ram etc the more likely your system is to be stable.
