Windows XP was designed to make it simpler to identify content on CDs or DVDs, and assist in launching the correct program to open or view the files.

For example, insert a movie DVD and Windows XP should show options for programs that can play a DVD. Unfortunately things can go wrong - settings get altered and the autorun no longer wants to be your friend. This free tool can help diagnose and repair autorun problems in XP.

It is a tiny download and doesn't require installation. Simply double-click the exe file, click a few buttons (OK, some options are a little cryptic) and you can change or repair your Windows XP autorun options.
