Office 2013 provides several settings that enable you to control the behavior of add-ins. By configuring these settings, you can do the following:
Disable add-ins on a per-application basis.
Require that add-ins are signed by a trusted publisher.
Disable notifications for unsigned add-ins.
You can configure add-in settings only on a per-application basis. There are no global add-in settings.
For information about how to configure security settings in the Office Customization Tool (OCT) and the Office 2013 Administrative Templates, see Konfigurieren der Sicherheit mithilfe des OAT oder Gruppenrichtlinien für Office 2013.
By default, any add-in that is installed and registered can run without requiring user intervention or warning. Installed and registered add-ins can include the following:
Component Object Model (COM) add-ins
Visual Studio Tools for Office (VSTO) add-ins
RealTimeData (RTD) servers
Application add-ins (for example, .wll, .xll, and .xlam files)
XML expansion packs
XML style sheets
This default behavior is the same as selecting the Trust all installed add-ins and templates setting in Office 2003 or an earlier Office system.
