COM+ Event System Registry

Applies To: Windows Server 2008

The COM+ Event System service provides automatic event distribution to Component Object Model (COM) components that subscribe to it. The functionality of the COM+ Event System service depends on consistency between the registry and the COM+ registration database. Each component attribute is stored in either the Windows registry or the COM+ Registration Database. New COM components are registered exclusively in the COM+ Registration Database, although there is some duplication in the Windows registry so that existing tools can use them.
