256986 Description of the Microsoft Windows Registry


SUMMARY

This article describes how to enable or disable automatically running CD-ROMs.

MORE INFORMATION

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

If there is a CD-ROM changer attached to your computer, you may want to disable automatically running CD-ROMs (the automatic running of a compact disc [CD] or the automatic playing of an audio CD-ROM). If automatically running CD-ROMs is enabled with a CD-ROM changer, each time that you insert a new CD-ROM into one of the trays, Windows cycles through every tray in the changer.

There is no option to enable or disable automatically running CD-ROMs in the user interface. To enable or disable automatically running CD-ROMs, you must edit the registry:

  1. Click Start, click Run, type regedit in the Open box, and then press ENTER.
  2. Locate and click the following registry key:

    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\CDRom

  3. To disable automatically running CD-ROMs, change the Autorun value to 0 (zero). To enable automatically running CD-ROMs, change the Autorun value to 1.
  4. Restart your computer.

NOTE: This method disables automatically running CD-ROMs. If you want to disable automatically running CD-ROMs depending on the CD-ROM that you insert in the CD-ROM drive, you can press and hold down one of the SHIFT key while you insert the CD-ROM.

Additional Information

There are two other registry keys that can affect this functionality:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer
NoDriveTypeAutoRun = 0x00000095

-and-


HKEY_USERS\.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer
NoDriveTypeAutoRun = 0x00000095


The correct value for each is 0x00000095.
