Hi Derek,
Reading Greg's multiple suggestions again, he/it does seem like some sort of automated bot replying by the (typical) obtuse manner of getting at a useful solution, but perhaps it's a real person that's just grown accustomed to answering in an MS approved way instead of finding/disclosing the regedit hack that just turns the bloody thing off.
I have had to do so many similar 'hacks' over the years that it's become tiresome, boring and futile expecting that they'll ever make it simpler and provide a simple toggle switch. As you say, there's absolutely no point in feeding-back, whoever/whatever makes these decisions in the first place has no intention of listening or to just simply making thinks blatantly easy to switch on or off. It's all done out of some sort of marketing or financial reward system and we all know how well that works for society, so hacks is all we have, I just wish they'd publish them in a useful resource of tweaks.
Thank you for listing your alternative solution, something that the theoretical/seemingly GregBot or MS could have done easily in answer to the original problem/question by 'Safes'.
