Microsoft Internet Explorer 5 (IE5) is the fifth, and by now, discontinued, version of the Internet Explorer graphical web browser, the successor to Internet Explorer 4 and one of the main participants of the first browser war. Its distribution methods and Windows integration were involved in the United States v. Microsoft Corp. case. Launched on March 18, 1999, it was the default browser in Windows 98 Second Edition, Windows 2000 and Windows ME and can replace previous versions of Internet Explorer on Windows 3.1x, Windows NT 3.51, Windows 95, Windows NT 4.0 and the original release of Windows 98. Although Internet Explorer 5 ran only on Windows, its siblings Internet Explorer for Mac 5 and Internet Explorer for UNIX 5 supported Mac OS X, Solaris and HP-UX.
