In Windows operating system such as Windows 7, Windows Vista, Windows XP, Windows Server 2003 and Windows Server 2008 (including R2 variants), the AutoPlay or AutoRun feature on USB, FireWire, eSATA and CD/DVD-ROM devices may not work with no dialog box displayed when external devices been plugged in.

Most VMWare virtualization products, such as VMWare Workstation, VMWare Player and VMWare Server, modifies the AutoPlay feature of Windows in some way or another in order to avoid conflict when a disc media is inserted into CD or DVD drive, or a device is plugged into the computer. The issue happens even though users have unchecked or unselected option to disable auto-run on VMWare.
