for some reason, the windows defender event log, as visible through the Windows Event Viewer application has stopped receiving new events. Previously, Windows Defender Antivirus would log events under Applications and Services Logs->Microsoft->Windows->Windows Defender/Operational. There, I could see when a scan started, completed, found/responded to malware, and other events.
However, starting a little over a month ago, the log in Event Viewer was no longer listed under its previous location and was instead directly inside the Application and Services Logs folder with the name "Microsoft-Windows-Windows Defender/Operational". In addition to this location change, no actions taken by Windows Defender are being added to this file.
The following is a screenshot of my Event Viewer with the log in changed location. In the screenshot, it is also visible that the last event recorded there was from over a month ago.
The following is the location in Application and Services Logs->Microsoft->Windows where I would previously have found a folder named "Windows Defender"
One thing that I considered is that there may have been some Windows Defender update that changed how it handled logging, however, this change in behavior has only happened on a couple of laptops I've checked, while others still operate as before. All devices I checked are running Windows 10. This is problematic for me since an application I am working on listens and responds to this event log, so while other machines are still functioning correctly, the app on my laptop and others with a similar issues can no longer respond to antivirus events. Does anyone know why my Windows Defender has stopped updating this log, and if there is a way to fix that?
