Microsoft Internet Explorer 5.0sp2 Official
By 1999–2000, Microsoft had successfully challenged Netscape Navigator's early market dominance. Internet Explorer 5.0 (often called IE5) was designed to be faster, more lightweight, and more deeply integrated into the Windows operating system.
Perhaps the most historically significant contribution of the IE 5 era was the introduction of the XMLHttpRequest object, originally implemented as an ActiveX control ( XMLHTTP ). Built to allow Outlook Web Access to fetch emails in the background without refreshing the entire webpage, this feature laid the groundwork for asynchronous web applications.

Microsoft released Service Pack 1 (SP1) to address some of these, but it was Service Pack 2 (SP2) that truly perfected the platform. Released alongside Windows Me and closely tied to the NT-based Windows 2000 ecosystem, IE 5.0sp2 became the enterprise standard for reliability and security just before Internet Explorer 6.0 took center stage with Windows XP.
