Uh, I believe Hard_Configurator is ESPECIALLY for "typical" users like me, if only they were lucky enough to come across it like I was. Probably moreso than for advanced users. A straightforward, unadorned, easy-to-read user interface devoid of jargon and techno-babble, something Microsoft hasn't been able to accomplish in the past three decades. One doesn't have to be Einstein in order to strengthen Defender's OOBE, to click a few boxes and know in general that protection is now strengthened and without sacrificing machine performance. Don't even have to hunt and search for obscure ways to harden Defender (that is, if you happen to already know these techniques are, in fact, out there and available to anyone).
I asked the developer one time about monetizing, using NVTOSArmor as a reference (which is a donationware). It's in this thread somewhere.
