Let us not forget that if you use some of the presets that come with SBIE, they are designed to keep some settings in the real system, such as bookmarks, etc. Depending on the configuration, simply deleting the sandbox does not delete everything that happened when it was sandboxed. Normally these settings only effect the user profile for something like firefox, not the program data. But, if you have changed an option for updating or something while in the sandbox, and you have it set to apply those changes to the real profile, then deleting the sandbox does not change what was saved in the profile. It all depends on the settings. Just something to think about. Sul.
