Minion saves its settings and games and addons in the Minion.xml.
Close Minion and use a backup of this file to restore it.
It should be somewhere in c:/users/... /appdata/.minion
If you got no backup of the xml file I guess you need to manually redo it.
in appdaata there is installation itself
.minion folder in the User folder
there is backup folder yes
but with empty 8 folders for each ESO game
without any backups of .xml file sadly
i think minion dont backup settings at all
