    Do you have to use Notepad++ ? If not, you can use Cygwin/Unix utilities and do this:

    grep -v -f text_file_b text_file_a
    

    This matches words from text_file_b (-f) against text_file_a and prints those that don’t match (-v)

    I appreciate this doesn’t use Notepad++, but I would advocate using the right tools for the right job, and I’m not sure an interactive editor is what you want here.
