Basic Examples  (1)

The default parallel kernel configuration:

When no kernels are running, LaunchKernels uses this list as the default to launch kernels:

Possible Issues  (2)

If any kernels are already running, LaunchKernels[] does not launch the default kernels:

Close all running kernels, then launch the default set of kernels:
