The topic I stopped opening Event Viewer after finding this buried Windows tool that actually… is currently the subject of lively discussion — readers and analysts are keeping a close eye on developments.
This is taking place in a dynamic environment: companies’ decisions and competitors’ reactions can quickly change the picture.
Regardless of how stable your PC is, Windows will occasionally run into an issue where it randomly crashes, an update fails for unknown reasons, or some other error occurs that you can’t pin down. For most people, the first instinct is to Google the problem or open Event Viewer. Both approaches are hit or miss, with Event Viewer using cryptic language and obscure error codes that you have to research to even understand.
The most useful way of quickly diagnosing the problem with your PC is to check Reliability Monitor. It’s been part of Windows since the Vista era, yet most users don’t think to reach for it. Reliability Monitor gives you a timeline of everything that’s gone wrong on your system, and it’s all presented in terms that are easy to understand. It makes it easy to identify problems, since there’s no need to parse logs or decipher event IDs.
The graph alone makes Reliability Monitor a useful tool. There’s a stability index scored 1 to 10 that dips visually whenever problems accumulate, and the timeline makes it easy to figure out when exactly things began going awry. Most of the errors on my graph are from failed Windows updates or a software install that went wrong. When you see a dip in the chart, that’s usually a good starting point when diagnosing a problematic computer.
The detail pane underneath the graph breaks events into categories: application failures, Windows failures, miscellaneous failures, warnings, and information. The informational events include things that went right, like software installs and uninstalls, successful Windows updates, etc. These categories make it easier to track down intermittent problems. for example, an unstable driver may not produce an error outright, but the stability index will steadily decline, and it’s easy to spot what happened when things began to degrade. Event Viewer contains all this same information, only it’s not nearly as accessible as Reliability Monitor makes it.
There’s a button at the bottom of the window that says “View all problem reports.” That link consolidates every crash and failure into a single list. If something keeps failing occasionally for the past week or two, this is the place to check how often it’s occurring and if the problem is improving or getting worse. When a family member hands me their laptop with a vague complaint about it crashing, it’s the first place I check to get a better read on its history before touching anything else.
Windows has a bad habit of burying some of its best tools deep in system menus. Reliability Monitor is one of the many victims of that habit. The path through Control Panel is a bit of a maze: system and Security > Security and Maintenance > Maintenance > View reliability history. If you’ve never found it before, that’s probably why. A better way to pull it up is by typing the name in Start menu. Once you do that, you can right-click and pin it to the Start menu for easier access in future.
One caveat to keep in mind is that the graph view only takes the past 28 days into consideration. You can still get a full list of all the problems that have occurred in the past for your PC, but the graph only reflects recent history. Because of that limited retention, the tool works better as one you check in on every once in a while. If the computer has been misbehaving for some time and you didn’t take a look, the graph view may not give you many hints about what’s wrong.
Reliability Monitor is great at identifying issues, but it doesn’t really help you fix them. You’ll be able to see that an application crashed, what caused it (sometimes), and when it happened, but what you do with that information is up to you. That limitation means that it probably shouldn’t be your only troubleshooting tool. Third-party apps like WhoCrashed are worth having in your toolkit, since they can provide you with deeper output to take action on.
I think of Reliability Monitor as my first step to diagnosing problems. It’s the tool that helps you understand what the issue is, and what event sparked it. for example, knowing that your crashes started happening right after a driver update is already half the battle. From there, you can attempt the actual fix, like rolling back the driver version.
It’s hard to believe that Reliability Monitor has been on Windows for the past two decades but barely gets mentioned in troubleshooting guides. Ever since coming across it, I rarely find a reason to open Event Viewer anymore. Once you’ve used it a few times, it becomes the obvious first stop whenever Windows starts acting up.
