You can configure settings for ActiveX controls, add-ins, and Visual Basic for Applications (VBA) macros by using the Office Customization Tool (OCT) and the Group Policy Object Editor.

Before you begin configuring settings, be sure you meet the planning requirements, administrative requirements, and tool requirements that are described in this section.

Use the following sections to determine how to configure settings for:

ActiveX controls

Add-ins

Macros

The following procedures show how to use the OCT and the Group Policy Object Editor to disable ActiveX controls and change the way ActiveX controls are initialized. To learn more about ActiveX control settings, see Security policies and settings in the 2007 Office system and Plan security settings for ActiveX controls, add-ins, and macros in the 2007 Office system.

You can use the following procedures to disable ActiveX controls. The settings described in these procedures apply only to applications in the 2007 Microsoft Office system; that is, ActiveX controls are not disabled in documents that are opened in earlier versions of Office. In addition, even though you disable ActiveX controls in a document, ActiveX controls still initialize and run without notification if a document is opened from a trusted location.

Disable ActiveX controls by using the OCT
  1. In the left pane of the OCT, under Features, click Modify user settings.

  2. In the tree view of the OCT, open Microsoft Office 2007 system and click Security Settings.

  3. In the details pane, double-click Disable all ActiveX.

  4. Click Enabled, select the Disable All ActiveX check box and click OK.

NoteNote:
You can also disable ActiveX controls by setting the Unsafe ActiveX initialization setting in the OCT to Do not prompt and disable all controls.
Disable ActiveX controls by using the Group Policy Object Editor
  1. In the Group Policy Object Editor tree, navigate to the following location:

    User Configuration/Administrative Templates/Microsoft Office 2007 system/Security Settings

  2. In the details pane, double-click Disable All ActiveX, click Enabled, select the Disable All ActiveX check box and click OK.

The following procedures show how to use the OCT and the Group Policy Object Editor to change the way ActiveX controls are initialized. ActiveX control initialization depends on several factors, including whether there is a VBA project present in a document and whether a control is marked safe for initialization (SFI) or unsafe for initialization (UFI).

Change the way ActiveX controls are initialized by using the OCT
  1. In the left pane of the OCT, click Office security settings.

  2. In the details pane, in Unsafe ActiveX initialization, click one of the following:

    Prompt user to use control defaults. This setting initializes ActiveX controls with default values and might require user input before ActiveX controls are initialized.

    Prompt user to use persisted data. This setting initializes ActiveX controls with persisted values and might require user input before ActiveX controls are initialized.

    Do not prompt. This setting initializes all controls and does not require user input.

Change the way ActiveX controls are initialized by using the Group Policy Object Editor
  1. In the Group Policy Object Editor tree, navigate to the following location:

    User Configuration/Administrative Templates/Microsoft Office 2007 system/Security Settings

  2. In the details pane, double-click ActiveX Control Initialization and click Enabled. In ActiveX Control Initialization, click the initialization setting that you want.

    There are six possible initialization settings for ActiveX controls. Some settings might require user input before ActiveX controls are initialized.

  3. Click OK.

The following procedures show how to use the OCT and the Group Policy Object Editor to:

  • Disable add-ins.

  • Require that add-ins are signed by a trusted publisher.

  • Disable notifications for unsigned add-ins.

To learn more about security settings for add-ins, see Security policies and settings in the 2007 Office system and Plan security settings for ActiveX controls, add-ins, and macros in the 2007 Office system

You can use the following procedures to disable add-ins. When you disable add-ins, users are not notified that add-ins are disabled. Also, add-ins can be disabled only on a per-application basis. There is no global setting that disables add-ins.

Disable add-ins by using the OCT
  1. In the left pane of the OCT, click Office security settings.

  2. In the details pane, under Default security settings, double-click Application add-ins warnings options for the application you want to configure.

  3. In the Specify Security Settings dialog box, click Disable all application extensions and click OK.

NoteNote:
You can also disable add-ins by setting the Disable all application add-ins setting to Enabled in the OCT.
