Because Configure Defender doesn’t have a marketing budget like ESET.I have a few friends on school who are strong advocates of ESET. When you have to spend time on learning how to tweak ESET (it has a great HIPS they say), why not just simply use DefenderConfigurator and max up WD? Why bother with HIPS, just run as basic user.
