> Plus users that use this stuff are self-selecting as the exact kind of users without the technical knowledge to know what they're doing, why, or how to undo it (or else they'd just make the changes "by hand") Or the exact kind of users at the other end of the bell curve, who are fully capable of "just mak[ing] the changes 'by hand'" but recognize that to be a massive waste of time when an automated solution can do it with orders of magnitude less time and effort (and do it again, when - not if - some Windows update undoes the changes).
