Information about how Microsoft updates the 2007 Office products
This article describes how Microsoft updates the 2007 Microsoft Office products.
Cumulative updating modelWhen we create an update or a hotfix for an Office program, for example for Word, the fixes that are included in the update or in the hotfix are cumulative. That is, the fixes are cumulative regarding the targeted files being updated within the specific Office product. The fixes are not cumulative regarding the whole Office system.
For example, if a hotfix contains a version of the Word file Wwlib.dll that was created on January 01, 2007, that hotfix contains all the changes that were made to the Wwlib.dll file until January 01, 2007. However, that hotfix may not contain updates for Excel.
For example, you apply an update rollup package that was released May 22, 2007, to Microsoft Office Word 2007. In this situation, you receive all the fixes that are contained in that rollup package as expected. However, you also receive all the fixes that are contained in the previously released rollup packages for Word 2007.
Note This method of updating the 2007 Office system is not intended to replace service packs for the 2007 Office system. Office service packs are also cumulative and all previously released hotfixes and updates are included. We also deliver additional product updates and features in service packs that are not available separately for the 2007 Office system.
Office updates and service packsAll versions of Office are serviced with cumulative updates. Updates for Office system components always contain the latest version of the affected file for that product version and all previously-released hotfixes to those files. Customers who have not installed the latest service pack (referred to as Service Pack N) and instead have the previous service pack (referred to as Service Pack N-1) can still install critical updates or important updates that are released for 12 months after the release of the most recent service pack (Service Pack N). Updates that install on Service Pack N and on Service Pack N-1 contain the same files and the same fixes. All fixes maintain backward compatibility together with previously-released updates.
When Service Pack 1 (SP1) is released, and you use a detection site such as Microsoft Update or Office Update, you will be offered SP1 and all updates that are released after SP1. However, you will not be offered any updates that were released before SP1. Any post-SP1 updates that you install will include all the SP1 fixes to that component.
After you install SP1, you will continue to be offered all updates that are released after SP1. In some cases, you may be offered updates for products that are not installed on your computer. Recommended updates are determined by the Office suite that is installed, not by the actual Office programs that are installed. For example, future updates for Microsoft Office Publisher 2007 will be offered for the installed Office Enterprise 2007 product even if Publisher is not installed.
Office service packs contain all previously-released fixes to all files in the products updated by the service pack. Service packs will install successfully regardless of whether other service packs or updates have been installed, including updates released after the service pack, except that service packs will not install if a later service pack has already been installed.

Automatic UpdatesCustomers who have enabled Automatic Updates will be automatically updated with the latest updates that have been released to Automatic Updates.
Computers that have Automatic Updates enabled will automatically be updated as follows:
- If the computer has a previous service pack that is still supported according to the terms of the Microsoft Support Life Cycle policy, and Microsoft has not enabled automatic updating for the latest service pack, Microsoft Update will install only the latest high-priority updates or important (for Office customers running Windows Vista) updates for that version of Office. The order of download or installation is as follows:
- Service Pack N-1 if the customer has an earlier service pack
- Pre-Service Pack N high-priority updates or important updates
- Post-Service Pack N high-priority updates or important updates
- If a user has a previous service pack that is still supported according to the terms of the Microsoft Support Life Cycle policy, and Microsoft has enabled automatic updating for the latest service pack, Microsoft Update will install both the latest service pack and the latest high-priority updates or important updates for that version of Office.
- If a user has a previous service pack that is not supported per the terms of the Microsoft Support Life Cycle policy, for example, it has been more than 12 months since the most recent service pack was made available), Microsoft Update will install the most recent service pack first. Then, Microsoft Update will install the latest high-priority updates or important updates after the most recent service pack is installed.
Critical or important updatesWhen Microsoft releases a high-priority update or an important update for a specific version of Office, the update will always target Service Pack N. The update will also target Service Pack N-1 for 12 months after the release of Service Pack N. In the case in which the fixis already included in Service Pack N, the update is intended for use with Service Pack N-1. However, the update will still target Service Pack N because the file version is more recent. In this case, customers who have Service Pack N would not have to install the update to fix the vulnerability that is described in the associated security bulletin. However, customers should install the update if they want to benefit from the fixes that are contained in the latest version of that file. Refer to the Knowledge Base bulletin article to determine whether the reported vulnerability is fixed in the latest service pack. If you have Service Pack N and use detection sites and tools, for example Microsoft Update, Microsoft Windows Server Update Services (WSUS), you will be offered security updates even when your installation may not be vulnerable at your service pack level. You may review security bulletins to verify the affected products.

Windows Software Update ServicesIf you are a Windows Software Update Services (WSUS) administrator, both the latest service pack and the post-service pack updates will be listed because both are applicable. However, post-service-pack updates that are released during the N-1 support period will still apply to the previous baseline. Pre-service-pack updates will not be available to the client computer until the most recent service pack is unapproved in the administrative interface.
For example, if you use WSUS to manage updates, you will see all available updates in the administrative console, both before SP1 and after SP1. However, if you approve SP1 in the console, pre-SP1 updates will not be offered to client computers. If SP1 is not approved, all updates will be offered to client computers.
