Opera Browser floods Windows Reliability Monitor with entries
Opera users running a recent version of the web browser on Windows may notice that the browser floods the Windows Reliability Monitor with entries.
Opera Software released Opera 89 Stable last week, and this version of the browser appears to be the culprit. The problem existed in development versions of the Opera browser and also migrated to the stable version of the browser. The development editions of Opera 90 also cause the problem.
The Opera browser launches and runs smoothly, and there are no noticeable startup or shutdown delays.
Dozens of entries are displayed in the Windows Reliability Monitor every time Opera is launched. The entries say “application reconfiguration successful” and list programs that are unrelated to Opera. This includes KeePass, Windows PC Health Check, Microsoft Visual C++ redistributables or Google Update Helper. It is unknown why these entries are added to the Reliability Monitor when launching Opera.
Microsoft explains that the Reliability Monitor provides a quick overview of the stability of a Windows PC:
Additionally, it tracks events that will help you identify the causes of reliability reductions. By recording not only failures (including memory, hard drive, application and operating system failures), but also key events regarding your system configuration (including installation of new applications and operating system updates), you can see a timeline of changes in system and reliability. Reliability Monitor also helps you identify how to bring your system back to optimal reliability when system behavior is not behaving as expected.
I confirmed the issue on a Windows 11 PC running Opera 89 Stable. Our colleagues at Deskmodder confirmed this on a Windows 10 PC.
Opera users running the browser on Windows can do the following to verify the issue on their devices:
- Use the Windows-R keyboard shortcut to open the run dialog.
- Type perfmon /rel and press the Enter key to launch the reliability monitor.
- It takes a few seconds to populate the list.
- Start the Opera web browser. Make sure it is Opera 89 or newer.
- Refresh the chart by clicking View > Refresh.
You should see dozens of new entries. Every time you restart or start Opera, you will notice that new entries are added to the reliability monitor.
The issue does not appear to affect browser functionality. Deskmodder has notified Opera Software of the issue, but has yet to receive a response. It is not known when and if the problem will be resolved.
Now you: do you use the Opera browser?
