How to enable or to disable the instantiation point of a specific COM category in an Office 2003 Service Pack 3 program
On This PageINTRODUCTIONThis article introduces a new feature in Microsoft Office 2003 Service Pack 3 (SP3). This feature lets administrators and users set registry keys in order to enable or to disable the instantiation point of a specific COM category in an Office 2003 SP3 program. For example, you can use this feature in Microsoft Office Word, Microsoft Office Web Components, or Microsoft Office Excel. Note This feature exists only in Office 2003 SP3. MORE INFORMATIONImportant This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base: 322756 (http://support.microsoft.com/kb/322756/) How to back up and restore the registry in Windows Enable or disable the new featureBy default, this new feature is disabled in Office 2003 SP3. To enable this feature, the following registry key can be set in the domain policy:HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\11.0\Common\Security
Value Value Name ComCatCheck
Value Type REG_DWORD Default Value None If this key is not set, users can set the following equivalent key for Office 2003: HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Common\Security Value Name ComCatCheck
Value Type REG_DWORD Default Value 0 Note The default value of 0 means that the feature is disabled. The default value of 1 means that the feature is enabled. Four categories are currently defined. For each category in Office 2003, there is a core domain policy category key as follows: HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\11.0\Excel\Security\COM Categories\CATID_ExcelCreateRTD HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\11.0\Access\Security\COM Categories\CATID_OWCSafeProviders HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\11.0\Word\Security\COM Categories\CATID_WordCreateLink HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\11.0\Word\Security\COM Categories\CATID_WordCreateOCX If these keys are not set, users can set the following equivalent keys for Office 2003:HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Excel\Security\COM Categories\CATID_ExcelCreateRTD HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Access\Security\COM Categories\CATID_OWCSafeProviders HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Word\Security\COM Categories\CATID_WordCreateLink HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Word\Security\COM Categories\CATID_WordCreateOCX The respective category IDs for these four categories are defined in the following table.
CheckType registry entry and CheckCatID registry entryYou can set the following registry entries in each category key.CheckTypeThe CheckType registry entry can be set to determine whether to use the Allow list or to use the Deny list.Value Name CheckType Value Type REG_DWORD Default Value 0 A value of 0 means that the deny list will be used. A value of 1 means that the Allow list will be used. Note If you set the value of the CheckType registry entry to 1 for a category and if you do not specify an Allow list, all controls in that category will be disabled. If you set the value of the CheckType registry entry to 0 for a category and if you do not specify a deny list, all controls in that category will be enabled. These guidelines are true unless the CheckCatID registry entry is set and is not present. CheckCatIDThe CheckCatID registry entry can be set to determine whether the category of the COM component must be checked.Value Name CheckCatID Value Type REG_DWORD Default Value 0 A value of 0 ignores the COM Category of the component. A value of 1 allows for COM components only in the specified category. Allow lists and Deny listsAllow listsThe Allow lists for four categories reside in the following locations:HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Excel\Security\COM Categories\CATID_ExcelCreateRTD\Allow
HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Access\Security\COM Categories\CATID_OWCSafeProviders\Allow
HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Word\Security\COM Categories\CATID_WordCreateLink\Allow HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Word\Security\COM Categories\CATID_WordCreateOCX\Allow Deny listsThe Deny lists for four categories reside in the following locations:HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Excel\Security\COM Categories\CATID_ExcelCreateRTD\Deny HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Access\Security\COM Categories\CATID_OWCSafeProviders\Deny HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Word\Security\COM Categories\CATID_WordCreateLink\Deny HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Word\Security\COM Categories\CATID_WordCreateOCX\Deny You can add a class identifier (CLSID) to the Allow list or to the Deny list. For example, to add CLSID {8BD21D40-EC42-11CE-9E0D-00AA006002F3} to the CATID_ExcelCreateRTD Allow list, you can create the following registry key:HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Excel\Security\COM Categories\CATID_ExcelCreateRTD\Allow\{8BD21D40-EC42-11CE-9E0D-00AA006002F3} You can add a CLSID to a specific category. For example, to add CLSID {8BD21D40-EC42-11CE-9E0D-00AA006002F3} to the CATID_ExcelCreateRTD category, you can create the following registry key:HKEY_CLASSES_ROOT\CLSID\{8BD21D40-EC42-11CE-9E0D-00AA006002F3}\Implemented Categories\{8F3844F5-0AF6-45C6-99C9-04BF54F620DA} Note The respective category ID for the CATID_ExcelCreateRTD category is {8F3844F5-0AF6-45C6-99C9-04BF54F620DA}.For more information about implemented categories, visit the following Microsoft Web sites: http://msdn2.microsoft.com/en-us/library/ms682451.aspx (http://msdn2.microsoft.com/en-us/library/ms682451.aspx) http://msdn2.microsoft.com/en-us/library/ms692674.aspx (http://msdn2.microsoft.com/en-us/library/ms692674.aspx) When you add a CLSID to a specific category for 32-bit applications on a 64-bit platform, you can use the following registry key:HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{CLSID}\Implemented Categories\{CategoryID} For more information about how to use the Group Policy snap-in to specify policy settings for groups of users and for groups of computers, visit the following Microsoft Web site:http://www.microsoft.com/technet/prodtechnol/windowsserver2003/technologies/directory/activedirectory/stepbystep/gpfeat.mspx (http://www.microsoft.com/technet/prodtechnol/windowsserver2003/technologies/directory/activedirectory/stepbystep/gpfeat.mspx) APPLIES TO
