disable Updates
To make setup disabled updates as default setting create/edit the fzdefaults.xml file in the setup folder. Set the option "Disable update check" to 1.
Maybe the users have already a settings file. Then you also need to change that under "\AppData\Roaming\FileZilla\filezilla.xml" of each user folder.
