Yes, I have heard of a non-admin account in windows.
I would love to know when you will be teaching the general public about this though. I am sure that it is something that my parents would like to attend as then dont know as much about windows as my little brother, and as I dont live with them any more I am sure it will be very useful so they can keep an eye on what is going on.
Can you not set it up for them? It's what I normally do...
Would you like to expand on this then?
From what I understand they could restrict access to a website that could be linked with copyright infringement. Youtube is part of google, hence google could be blocked (I may of got this wrong though).
To block a site under the new rules, the public has to be consulted and a statutory instrument created before ISPs are compelled to block it, and there would need to be demonstration of 'serious adverse effect on business or consumers' and evidence that the bulk of the material involved serious breach of copyright. It would simply not apply to Google (or even youtube, given the restrictions on youtube and their policy of quick response in the event of a complaint).
