Jen, tagging on to an old post (especially one from a poster who has since been banned from the forums) is not a good way to get your question noticed.
When working with the registry, I don't suggest using batch files. Use REGEDIT interactively, create a backup copy before making any changes, and keep your wits about you.
Many AV and malware scanners create .reg files so you can back out any changes they made. Creating your own can create unforeseeable (read: fatal) problems.
