Default Behavior

Device Association Service is a Win32 service. In Windows 10 it is starting only if the user, an application or another service starts it. When the Device Association Service is started, it is running as LocalSystem in a shared process of svchost.exe along with other services. If Device Association Service fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the DeviceAssociationService service has failed to start due to the error.

Restore Default Startup Configuration for Device Association Service

1. Run the Command Prompt as an administrator.

The DeviceAssociationService service is using the das.dll file that is located in the %WinDir%\system32 folder. If the file is changed, damaged or deleted, you can restore its original version from Windows 10 installation media.
