Tip: Disable Autorun In Windows XP / 2000

Filed under: — By Aviran Mordo @ 12:16 pm

When you insert a new CD into your CD-ROM drive windows is configured by default to automatically search and run a file called autorun.ini in your disc. This file contains instructions of what to do when this disc is inserted in your drive. Usually this file starts a setup program, or some sort of a menu.

Although most of the times this will benefit you, since you don’t have to browse the CD and manually start the application, sometimes this behavior can cause problem or even misuse.

A recent example of this being misused is in the case of Sony’s DRM rootkit, which installed itself without you knowing, taking advantage of the auto run feature.

Fortunately we can easily disable this option, so nothing will run automatically when we insert a CD into the drive, hence no suspicious DRM application or other software running without our explicit consent.

To disable autorun follow these steps:

  • Open the Registry Editor (REGEDIT.EXE).
  • Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cdrom.
  • Double-click on the Autorun value, and set the value to 0.

You may need to restart your machine in order for this to take effect.
