Само-то уведомление убрать можно — The Bat! Help: Цитата: Confirmations Using the Options -> Preferences -> Other options -> Confirmations menu you can specify the actions that need a confirmation. If you set a confirmation for an action, you will get a warning when you try to perform this action and you will be able to cancel it. If you do not set a confirmation, the action will be performed without warning. For example, if you enable "Check for update when The Bat! starts", the program will inform you of a new version when it is available. »
