Anandraj, welcome to the JBoss Community!
It is the JBoss AS code itself that decides to use 'default' if you don't specify a configuration to run. Here are two typical mechanisms used to do what you want:
a) Edit run.bat to pass "-c all" to the command that starts the app server
b) Create another bat file, such as runall.bat, which contains this line: call run.bat -c all
Personally, I prefer option (b).
