How to Block All Websites Except One

You might want to block websites for school filtering, parental controls or any number of reasons. Web browsers have different built-in controls for website filtering, and security software such as Norton or McAfee have their own options. Blocking can be achieved in many different ways, but Windows Vista offers the most straightforward method for blocking all websites except one using its User Controls feature.
