Opera users who run a recent version of the web browser on Windows may notice that the browser is flooding the Windows Reliability Monitor with entries.

Update: Opera Software has fixed the issue.

Opera Software released Opera 89 Stable last week, and this browser version appears to be the culprit. The issue existed in development versions of the Opera browser and has migrated to the stable version of the browser as well. Development editions of Opera 90 are causing the issue as well.

Opera browser launches and works without issues, and there is no noticeable startup or shutdown delay.

Dozens of entries are displayed in the Reliability Monitor on Windows whenever Opera is launched. The entries state "successful application reconfiguration" and list programs that are not related to Opera. This includes KeePass, Windows PC Health Check, Microsoft Visual C++ redistributables, or Google Update Helper.  It is unclear why these entries are added to the reliability monitor when Opera is launched.

Microsoft explains that the Reliability Monitor provides a quick view of a Windows PC's stability:

In addition, it tracks events that will help you identify what causes reductions in reliability. By recording not only failures (including memory, hard disk, application, and operating system failures), but also key events regarding the configuration of your system (including the installation of new applications and operating system updates), you can see a timeline of changes in both the system and reliability. The reliability monitor also allows you to identify how to get your system back to optimal reliability when the behavior of the system is not behaving as expected.

I have confirmed the issue on a Windows 11 PC running Opera 89 Stable. Our colleagues over at Deskmodder confirmed it on a Windows 10 PC.

Opera users who run the browser on Windows may do the following to check the issue on their devices:

  1. Use the keyboard shortcut Windows-R to open the run box.
  2. Type perfmon /rel and hit the Enter-key to launch the Reliability Monitor.
  3. It takes a few seconds to populate the listing.
  4. Start the Opera web browser. Make sure that it is Opera 89 or newer.
  5. Refresh the chart with a click on View > Refresh.

You should see dozens of new entries. Whenever you restart or start Opera, you will notice that new entries are added to the Reliability Monitor.

The issue does not seem to impact the browser's functionality. Deskmodder notified Opera Software about the issue, but have not heard back yet. It is unclear when and if the issue will be fixed.

Now You: do you use the Opera browser?

    I use Opera sparingly on Windows, but not on Ubuntu, as I had problems with it there.
    I can’t remember what they were. It is very slow on both platforms. Perhaps the problem you mention has been around for some time – just not noticed.

    Opera has generally been tardy in fixing problems, or at least telling me how to fix the problem.

    Can’t test it because I disabled Reliability Monitor, which is pretty easy to do just like anything non crucial on windows even if it is locked by system like Defender.

    But I guess we have to hope Opera fixes it soon even if it doesn’t really affects me.

      That wouldn’t matter, since Reliability Monitor is just a front-end for Event Viewer, so these events should be there somewhere. This particular one likely is an Msapplication event in the Application log.

        Well, then it matters because the article is wrong. The reliability monitor gets “flooded” not because reliability monitor but because of EventLog, which I had also disabled anyway so nothing was getting registered.
        These are entries in Application – Windows Logs in the Event Viewer, so that’s why they appear in the monitor, it’s reliability monitor functionality to display these log entries but they have nothing to do with the monitor itself, so the article should be accurate about it.
        Reliability Monitor has its own report system, which is the one that appears when you click “View all problems reports”, and that report system is done through WER and not the EventLog itself, so you only disable reliability monitor reports by disabling WER. If WER gets affected by also disabling EventLog, I don’t know, but this issue is logged by EventLog service and not the WER (that’s my whole point).

        Anyway, Event Viewer says that the source is MsiInstaller so whatever Opera is trying to do on start, is calling MsiInstaller, but it only happens when you open Opera so so it will obviously not affect Opera performance in anyway once it is opened and loaded. It is weird it happens though, and Opera team should correct it like… today.

    Win 21H2 19044.1766 + OB 89.0.4447.38 = I have no any errors. Someone has a mess on their system and is having problems. This is not a general-opera problem as the title might suggest.
