Updates to Office 2003 include changes made in Office 2003 Service Pack 3

David [Microsoft] — Tue, 15 Apr 2008 03:35:00 GMT

As you may know, Office 2003 Service Pack 3 contains some changes to the behavior of Office. For example, certain file types cannot be opened or saved by default, although you can re-enable this functionality by setting registry keys as described in this Microsoft Knowledge Base article and on David LeBlanc’s blog. A common question is whether these behavior changes are included in post-SP3 security updates. In short, yes: security updates released after SP3 contain behavior changes first released in SP3, even if you do not have SP3 installed. This post will briefly describe why that occurs and will outline which updates contain which changes.

For several reasons, Office patches are cumulative - broadly speaking, they contain all changes from previous updates to the same component, including service packs. By “component”, we mean the set of files in the patch - typically, this is the file or set of files like excel.exe that define the core, central functionality of an application. We plan to provide a more thorough explanation in a future post. The key thing to know for this discussion is that the latest update to Excel will contain SP3 changes in Excel, including behavior changes, and likewise for the other Office applications. This occurs even if SP3 has not been installed - if you have SP2 installed and install a security update released after January 1st, 2008, you will see the SP3 behavior changes. The information in this post applies to all update types, including security updates, non-security updates, and hotfixes.

Below, you will find a list describing which changes are contained in which updates. For the most part, the title of an update should make it clear which product is affected - for example, “Security Update for Microsoft Office Word 2003” is an update for Word. A few files like mso.dll and cdrimp32.flt may be more confusing. These files are typically contained in updates called “Security Update for Microsoft Office 2003”, and you can determine exactly which files are affected by such an update by consulting the “File Information” section of the security bulletin.

· Office 2003 can now be configured to allow or deny specific COM components. For more information, see Microsoft Knowledge Base Article 938815.
