Have you ever wanted to backup Internet Explorer's settings? Now, there's a third-party tool that will do just that: Backrex Internet Explorer
The small, step-by-step backup program grabs everything from Internet Explorer 6 or 7, including cookies, add-ons, auto-complete entries, connection settings, and, of course, your favorites .You back it all up to a zip file that's compressed and, if you'd like, password-protected, and can restore settings in the same click-by-click fashion.
The app doesn't support the Internet Explorer 8 betas (yet).
