+ Pause.
Or right click on the 'My Computer' or 'Computer' folder and click 'Properties'.
To find out what add-ons you are using have a look in the 'My Programs' or 'Programs and Features' folder in the control panel.
An add-on is something that you install and it links its self to messenger. MP!L is an add-on. Can you remember adding any other programs that claim to make messenger better?
