What's wrong is that there is no error message or output. Unless there was one and you forgot to tell us ;-).

On Windows strings are delimited by " rather than '. It does output an error when I try this: echo '^(GUI_|AA_|myMainScript)'
'AA_' is not recognized as an internal or external command, operable program or batch file.
