I was under the impression that that the software contained virus. Now i know it it isnt a virus but it could be still be dangerous. Once you enter it, it seems it will be stored forever!. So someone could make use of this . If you don?t want to be nagged by the balloon, use this hack to disable the reminder forever.
Navigate to:
HCU\Software\Microsoft\MessengerService
Change the Binary Value PassportBalloon to 0a 00 00 00 to permanently disable the reminder.
