Microsoft released the Office 2003 Service Pack 3 just a few hours ago which contains the latest updates for Office 2003. The pack with a size of 117 Megabytes contains 22 security patches and updates as well as the previous two service packs for Office 2003. The main emphasize of this service pack seems to be security related because 14 of the 22 updates are security related.

Besides the security update Office 2003 Service Pack 3 contains also stability improvements which have been implemented after receiving enough user feedback on several issues. There is no Windows Genuine Advantage check before you can download the new service pack and I assume there will also be none when installing it.

All important applications like Word 2003, Excel 2003 and Outlook 2003 receive at least one security update. Cautious users can also download and install updates separately if they feel that they do not want to download the 117 Megabytes.

Please note that you only need to install the third service pack even if you have not installed Service Pack 1 or 2 for Office 2003 yet. This can also be helpful when you reinstall the program on the computer or another device.

As far as new and updated features go, there are a few noteworthy ones:

  • After you install Office 2003 SP3, you can use a registry key to enable or to disable the instantiation point of a specific COM category in an Office 2003 program.
  • After you install Office 2003 SP3, you can use a registry key to change the number of embedded MIME messages that are processed before a MIME message appears in the message body in Outlook 2003.
  • After you install Office 2003 SP3, you can install add-ins in Microsoft Office Access 2003 on a Windows Vista-based computer.

You can download the third service pack for Office 2003 from Microsoft's Download Center.
