The software maker released what it calls an Update Rollup for the 5-year-old operating system, which is due to shift at the end of this month from receiving mainstream support to extended support. Microsoft does not generally add features to a product under extended support, and the Update Rollup is largely a collection of previously released patches as opposed to a batch of new features.
In addition to already released fixes, the collection "may contain fixes for non-public low- and moderate-level security issues that did not warrant individual security bulletins," a Microsoft representative said.
The Redmond, Wash.-based software maker said last November that it would release the Update Rollup rather than offer a fifth service pack. As a result, the final service pack for Windows 2000 becomes the SP4 release that came out in March 2003.
Although Windows 2000 has been followed by several other Windows versions, the software remains extremely popular in corporations and small businesses. It still accounts for nearly half of all Windows-based business desktops, according to a recent survey by AssetMetrix.
