Microsoft Internet Explorer 3.0 This version of Windows 95 (4.0.950b) comes with Microsoft Internet Explorer 3.0 automatically built in. You do not need to install Internet Explorer separately. However, if you do install a stand-alone version from the internet or from any other source, and then uninstall it, it will not automatically restore the original version included with this version of Windows 95. You may therefore need to either reinstall Windows 95 from your CD, or you may simply run the MSIE30.EXE program in this directory.
