How to fix OneCore-DeviceAssociationService error ID 3503 in Windows?

After upgrading to Windows version 24H2, some users have reported encountering the “OneCore-DeviceAssociationService” error with Event ID 3503 in the Event Viewer. This error is accompanied by the message: “The Device Association Service detected an error discovering endpoints.”

Event Viewer in Windows is a utility that logs system notifications, errors, and warnings. Though seeing a list of errors may raise an alarm, it should be understood that not all of them require immediate attention or signal a critical problem. Many logged errors are benign and don't impact the system's performance or functionality.

In the case of the OneCore-DeviceAssociationService error ID 3503, users have noted its appearance following system shutdowns or restarts after the 24H2 update. Despite the error log, most have observed no noticeable issues with their system's operation. This suggests that, for the majority, this specific error doesn't adversely affect daily use and can be considered non-critical.

However, if you prefer a clean Event Viewer or are concerned about potential underlying issues, you might choose to address this error. Optional instructions that could help resolve it are provided below.
