Change Default Prompt

I know that in Windows itself you can change the default command prompt so when you execute prompt from the command line you get your own default prompt instead of the default $p$g, However I haven't figured out how to do it in Take Command nor TCC.

How do you change it so that if I do prompt for the TCC command line, I get my prompt not [C:\]. I have color and several things added.

Thank you,

George
