If you place your CD in the drive and it doesn't autoplay, there could be several reasons.

  1. If the CD does not contain a file called autorun.inf in the root directory, it is not designed to autoplay.
  2. If there is a syntax error in the autorun.inf file, the CD will not autoplay.
  3. If the autorun.inf file instructs the system to open a program, but the program cannot be located in the path provided, the CD will not autoplay.
  4. If your Registry is set to inhibit autoplay on the CD drive, it will not autoplay. Right click on the CD's icon. If the word "Autoplay" does not appear in the drop down menu, the CD is not enabled for Autoplay.

If your autorun CD won't autoplay, it could be that your Registry autorun setting has been turned off. There is always a risk when you attempt to make modifications to your Registry, especially if it is an unfamiliar task. Tweak UI provides a user friendly interface to make common Registry changes with minimum risk.
