Disable the Windows Messenger

Here you also use the registry editor program to do this trick. First type "regedit" in the "Start | Run", click OK, and wait until the registry editor appears. After that, go to the entry "HKEY_CURRENT_USER | Software | Microsoft | Windows | Current Version | Run." Point your mouse at the right window and delete the entry named "MSMSGS." Once cleared, close the program registry editor. With this step, then you will not find Windows Messenger to the Windows Start time, so you do not disrupted again on the task.
