Here is the top level link
The updates can be checked
from Here
This month's updates were 17MB (for my version of Office2003) and required a reboot and the insertion of the original Office CD (upon reboot of WinXP) and upon attempting to relaunch Word® for the first time.
In addition to the security patches and software updates, the first link (above) may also allow you to download other helper utilities and other FREEware downloads that you may be interested in.
If you have additional time in your hands, you can also join to subscribe/receive their
Office NewsLetter.
Enjoy!
