Internet Explorer 4

Internet Explorer 4 is a version of Internet Explorer, released in October 1997 for Windows and 1998-01-06 for the Mac OS. It can run on Windows 3.1, 95, 98, Mac OS 7.1+, and Solaris. Installing Internet Explorer 4 on Windows 95 or Windows NT 4.0 enables the 'Windows Desktop Update', which adds Internet Explorer integration to various parts of the OS. This includes replacing the traditional Windows Explorer with a web browser-like interface, and Internet-enabling the desktop itself via Active Desktop (which includes the infamous 'channel bar' of advertising links). Internet Explorer 4 shipped with Windows 98 and was later released for Macintosh.

This version also updates parts of the logo branding, using the well-known "E" icon.
