Windows 2000 has received four full [[service pack]]s and one rollup update package following SP4, which is the last service pack. Microsoft phased out all development of its [[Java virtual machine|Java Virtual Machine]] (JVM) from Windows 2000 in SP3. Internet Explorer 5.01 has also been upgraded to the corresponding service pack level.

Service Pack 4 with Update Rollup was released on September 13, 2005, nearly four years following the release of Windows XP and sixteen months prior to the release of Windows Vista.

Microsoft had originally intended to release a fifth service pack for Windows 2000, but cancelled this project early in its development, and instead released Update Rollup 1 for SP4, a collection of all the security-related [[hotfix]]es and some other significant issues.<ref>{{Cite web |last=Naraine |first=Ryan |date=November 26, 2004 |title=Microsoft Scraps Plans for Windows 2000 SP5 |url=http://www.eweek.com/c/a/Windows/Microsoft-Scraps-Plans-for-Windows-2000-SP5/ |url-status=live |archive-url=https://archive.today/20130122223337/http://www.eweek.com/c/a/Windows/Microsoft-Scraps-Plans-for-Windows-2000-SP5/ |archive-date=January 22, 2013 |access-date=May 30, 2009}}</ref> The Update Rollup does not include all non-security related hotfixes and is not subjected to the same extensive regression testing as a full service pack. Microsoft states that this update will meet customers' needs better than a whole new service pack, and will still help Windows 2000 customers secure their PCs, reduce support costs, and support existing computer hardware.<ref>{{Cite web |title=Windows 2000 Update Rollup 1 for Service Pack 4 |url=http://www.microsoft.com/windows2000/server/evaluation/news/bulletins/rollup.mspx |archive-url=https://web.archive.org/web/20060113110336/http://www.microsoft.com/windows2000/server/evaluation/news/bulletins/rollup.mspx |archive-date=January 13, 2006 |access-date=September 27, 2006 |publisher=Microsoft}}</ref>
