AutoRun feature of Windows OS automates the procedures for installing and configuring products designed for Windows-based platforms that are distributed on CD-ROMs. When the users insert an AutoRun-enabled CD into the drive, it automatically runs the application on the CD-ROM. AutoRun works only if the system is running either of the OS - Windows 95, Microsoft Windows NT 4.0, or later versions. AutoRun is used for distributing applications on CD and DVD for public use. It is found useful also on other removable storage media. It starts as soon as it is inserted. The 32-bit device drivers enable the system to send the media change notification message to Windows interface and all the media related features are activated like AutoPlay. If the message is disabled then the media related features are also disabled.
