I'm no expert on this, but I believe that this is for the user's own protection; in order to prevent malicious attempts to subvert security and mess with the user account specified scheduled tasks that you have set-up. When Windows executes a scheduled task, the Scheduled Task service first creates a new logon session for the task so that it can run under the authority of the user account specified when the task was created.
