Karen’s Autorun.inf Editor
Easily create the Autorun.inf file that allows programs on CD run automatically when the CD is inserted! Now the CDs you create can automatically display a web page, text file, navigate the user’s web browser to a support web site, launch an exe program, pretty much anything. It lets you choose a CD icon too.

She has created some other useful powertools too like the Registry Pruner.
