Super User is a question and answer site for computer enthusiasts and power users. It's 100% free, no registration required.

The situation:

  • There is a windows 7 machine that can connect to internet only through an organisation's proxy.
  • I have no control over the proxy servers.
  • There is a single administrator account on the machine, and I do not wish to set up a limited account.


  • How can certain domains be blocked, so that the user can not access them without some unblocking?
  • The user is non technical and is not adamant, hence simple solutions should work effectively.


  • Hosts file doesn't work since all requests are routed through proxy server.
  • Configuring the existing proxy is the easiest thing but I'm not allowed access.
  • Firewall, parental control in Antivirus ( I've tried just trend micro) and blocking from internet options all dont work.


  • Having to install a software is OK.
  • Any pointers to achieving this using some kind of scripting are OK. ( intercepting all GET/POST requests and rerouting on pattern matching)

Windows 7. just edited the question. – Mahesh Oct 11 '12 at 11:33
If you edit the hosts file to point such addresses to the localhost it should effectively block them. – Lizz Dec 14 '12 at 6:09
