Microsoft said the update will contain all security-related updates produced for Windows 2000 between the time SP4 was released and the release of the update. It will also contain a small number of important non-security updates.
Nick McGrath, head of platform strategy at Microsoft, said the update would be the last patch bundle for Windows 2000. After its release, McGrath said, "There will only be hot-fix releases."
Microsoft said that by including the most important updates for Windows 2000, the Update Rollup will make it easier for customers to keep existing Windows 2000 systems secure and up-to-date and to build new deployment images.
It claimed the Update Rollup will require less pre-deployment testing as the number of updates is lower than the number typically included in a service pack.
Microsoft said SP4 would be the final service pack for Windows 2000. "Customers who have not yet deployed SP4 should consider deploying it as soon as possible, especially as it will be a prerequisite for deploying the Update Rollup," it said.
