3.In the right pane, right click on any blank space, select New on context menu, and then click on DWORD (32-bit) Value.
4.Name the new registry value entry as MultipleInstances.
5.Modify the MultipleInstances and set its value data as 1.
6.Start as many Windows Live Messenger windows as you want from Start Menu.
