The Updater can preserve your Express Gate settings and personal data (web
browser bookmarks, etc.) while doing an update. Use the checkbox “Keep user
profile” to decide whether the Updater should do so.
Clearing the user data is useful in the rare case where corrupt settings prevent the
Express Gate environment from launching properly.
The first time wizard will run again when you enter the Express Gate
environment after clearing its settings.
