The current service pack for the Windows Vista operating system is Service Pack 2.
Microsoft Office versions 2003 and 2007 both have Service Pack 3 updates. If you are offered Office Service Pack 3 via Vista Windows update, you probably have one of those office editions on your computer. It may be a trial version that was never activated. Since service packs are bug fixes, security updates, and general improvements, it is usually a good idea to install them if the software is on your computer, even if you don't use the program. Second option would be to uninstall office.
