Windows 10: blocking websites in any browser using local host or other method

I'm interested in blocking content on a local machine, but now allowing the user to look up how to unblock this stuff. so for instance, if I want to block a local user, who operates their own machine, from going to this site: https://www.youtube.com/ , how exactly would I do that without having any control over undoing it? So for instance, what I'm saying is that I'd like to block sites from rendering on a machine and sort of "password protect" the solution in a way where no one knows the password. Thus, the blocking can't possibly be undone. Has anyone done anything like this before? I have looked it up, which I was aware of this method before, but I don't think would do any good because this could easily be undone:

anybody got any ideas on how to do this in the manner I'm interested in?

List website to block in host file

So , recent I learn that I can block the ads on my pc if I put the ip address of that ads in the host file to go on 127.0.0.1, well I did not escape from all ads but I am not rely only on browser addons(take some work on cpu), also I like host idea because I can control it and block before enter on pc, not on browser, I put the list from here:
http://winhelp2002.mvps.org/hosts.txt
now I see another list who seems good too:
http://www.malwaredomainlist.com/hostslist/hosts.txt

I know this lists are not forever,I must check periodical for changes, but I want to know if are another, maybe, best list(updated periodical).

Look like the one from malwaredomainlist.com it is to aggressive, even yahoo messenger will not connect, so I will stay with http://winhelp2002.mvps.org/hosts.txt for now, maybe athers will post their finds.

 

Blocking website using 27.0.0.1 local host

Hi. I was having a problem opening up a customer login on a car insurance website and when I googled why this would be, I discovered that my pc has listed this and a couple of other sites on the local host to block my access to it. This is my personal machine
but my ex as an IT Consultant is still administrator on all our systems. However, several of the domains listed is for a bank and although still listed to be looped back to my IP address, and therefore blocked by the loop, they do still work...how is this
possible? Is the fact that they are approved by VeriSign make a difference? The other domains blocked don't work and loop back to my machine. This is isn't a corporate issue as I think was mistakenly assumed in last response. Thanks.

How to Block Websites
