From Microsoft:

SUMMARY This article describes Update Rollup 1 for Microsoft Windows 2000 Service Pack 4 (SP4). Update Rollup 1 for Windows 2000 SP4 was released June 28, 2005. This update rollup contains a list of security-related updates produced for Windows 2000 between the release of Windows 2000 SP4 and April 30, 2005. April 30, 2005 is the date when the contents for Update Rollup 1 were locked down for final testing by Microsoft, external beta testing sites, and customer sites. Additionally, this update rollup contains several important non-security updates. This article contains detailed information about this update rollup, answers frequently asked questions about this update rollup, and lists the fixes that are included in this update rollup.

By including the most important updates for Windows 2000, Update Rollup 1 for Windows 2000 SP4 helps customers to make existing Windows 2000-based computers more secure and up to date. Update Rollup 1 for Windows 2000 SP4 will also make it easier for customers to build new deployment images. This update rollup should require less pre-deployment testing because the number of updates included in Update Rollup 1 for Windows 2000 SP4 is significantly smaller than the number of updates that are typically included in a service pack. Most customers will have current versions of many of the files already installed from prior updates. Additionally, Microsoft will have already released most of the contents of the update rollup as individual updates and hotfixes. Individual hotfixes that are not included in this update rollup and that are released after Windows 2000 SP4 was released will be available as individual downloads.

Because Microsoft believes that Update Rollup 1 for Windows SP4 will meet the needs of customers better than a new service pack for Windows 2000, Microsoft will not release a Service Pack 5 for Windows 2000. Therefore, Windows 2000 SP4 is the final service pack for Windows 2000. Customers who have not yet deployed Windows 2000 SP4 should consider deploying Windows 2000 SP4 as soon as possible. Windows 2000 with SP4 is a prerequisite for Update Rollup 1 for Windows 2000 SP4.
