My operating system is Windows 7 Starter.
I need a software solution, I'm well aware of the built in options of Windows 7, but the rules are no limited accounts, no accounts at all, something (a firewall?) able to block all HTTP traffic except the one coming from a single website. I've seen several solution (cyber nanny and the likes) but they are a bit expensive and full of features I'll never use.
I thought I could do it with the hosts file but it doesn't support wildcards. :-(
