The most part of the data (including the configuration of applications, structure of the menu and the registration information) is kept in the "...\Application Data\MetaProducts User Files\tm.tdf" file.
Preservation of this file will allow you to keep practically all information on settings of TrayIcon.
Its connection to TrayIcon is carried out by simple replacement on necessary file.
The part of settings is stored in registry "HKEY_CURRENT_USER\Software\MetaProducts\TrayIcon Menu".
