The process of removing Internet Explorer from a personal computer has changed over the browser's version history, but the nature of many of its upgrades and installation methods has been a matter of public interest. The first version to be included was version 2 with Windows 95 in late 1996. Later, users who upgraded to IE3 (which came out in 1996), could still use the last IE, because the installation converted the previous version to separate directory. However, Internet Explorer 4 created a controversy with its shell integration with Windows Explorer. With later versions removal (or inability to do so) became more complicated. With the release of Internet Explorer 7, shell integration began being reduced, such as changing ActiveX hosting and a different look than Windows Explorer.
