When an appropriately configured <a href="/wiki/CD-ROM" title="CD-ROM">CD-ROM</a> is inserted into a CD-ROM drive, Windows detects the arrival and checks the contents for a special file containing a set of instructions. For a CD containing software, these instructions normally initiate installation of the software from the CD-ROM onto the hard drive. To maximise the likelihood of installation success, AutoRun also acts when the drive is accessed ("<a href="/wiki/Double-click" title="Double-click">double-clicked</a>") in <a href="/wiki/Windows_Explorer" class="mw-redirect" title="Windows Explorer">Windows Explorer</a> (or "My Computer"). </p><p>Until the introduction of <a href="/wiki/Windows_XP" title="Windows XP">Windows XP</a>, the terms AutoRun and AutoPlay were used interchangeably, developers often using the former term and end users the latter. This tendency is reflected in Windows Policy settings named AutoPlay that change Windows Registry entries named AutoRun, and in the <a href="/wiki/Autorun.inf" title="Autorun.inf"><code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">autorun.inf</code></a> file which causes "AutoPlay" to be added to drives’ <a href="/wiki/Context_menu" title="Context menu">context menus</a>. The terminology was of little importance until the arrival of Windows XP and its addition of a new feature to assist users in selecting appropriate actions when new media and devices were detected. This new feature was called <i>AutoPlay</i> and a differentiation between the two terms was created.<sup id="cite_ref-autoplaydiff_1-0" class="reference"><a href="#cite_note-autoplaydiff-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p><p>AutoRun, a feature of Windows Explorer (actually of the shell32 <a href="/wiki/Dynamic_Link_Library" class="mw-redirect" title="Dynamic Link Library">dll</a>) introduced in Windows 95, enables media and devices to launch programs by use of command listed in a file called <code class="mw-highlight mw-highlight-lang-text mw-content-ltr" style="" dir="ltr">autorun.inf</code>, stored in the <a href="/wiki/Root_directory" title="Root directory">root directory</a> of the medium. </p><p>Primarily used on installation CD-ROMs, the applications called are usually application installers.
