How to Enable or Disable CD AutoRun

Do you get annoyed when CDs AutoRun?  Some users find this bothersome. The level of annoyance may depend on what kind of CD is being inserted into your system.

To prevent CD AutoRun, you can choose to have the CD AutoRun universally disabled instead of disabling based on individual file types.

This is a registry tweak designed for Windows XP and will universally disable CD AutoRun.  However, modifying your registry carries inherent risks.  To minimize these risks, you should create a back-up before implementing any changes to your registry.

Here are the steps to follow when enabling or disabling CD AutoRun.

  1. Click Start.  Go to Run.  Enter regedit and wait for the registry editor box to pop up.
  2. Go to HKEY_LOCAL_MACHINE which can be found on the left side of the box.  You can expand this and all other folders by clicking on the little cross found at the left of each folder.
  3. Now go to SYSTEM.  Expand this folder.
  4. Once you’re done expanding SYSTEM, look for CurrentControlSet listed underneath.
  5. Expand CurrentControlSet until you find Services.
  6. Expanding Services will take you to CDROM.
  7. Now, look at the right side of the box.  Check if DWORD value AutoRun is present.  If the value is listed, skip ahead to step eight.  If the value is not listed, create AutoRun by following instructions below:
  8. 7a. Right click on the white part of the right side pane.

    7b. Select New and then select DWORD.

    7c. Rename the new value AutoRun.  You can also rename the new DWORD value by right clicking on the value and selecting Rename.

  9. Double click on AutoRun.  A small box should pop up.
  10. Enter 0 to disable AutoRun.  Alternately, you can enter 1 to enable AutoRun.
  11. Exit the registry and reboot.
