Wow, there sure is some crazy stuff in that link. I would not touch that stuff with a stranger's computer, let alone mine.
P.S. This should have gone in the discussion section not in the support section.
I concur with your first statement, at least on the whole, hence my disclaimer.
As to it belonging in the discussion section, I'd agree except for the fact that virtually every question that's ever been asked about how to nuke this or that under Windows 10 has been asked here.
There are tweaks that I'm willing to make and have made (not from that page) but as far as the extent of changes documented there all I could think is, "Stupid is as stupid [paranoid] does."
