How to Disable the Content Advisor
In versions of Internet Explorer prior to version 10, the Content Advisor feature was enabled by default. As of IE version 10, the functionality of the Content Advisor feature can be achieved with the new Family Safety filtering tool. Therefore, the Content Advisor feature has been deprecated and is disabled by default. If you have enabled the Content Advisor and you now wish to disable it, do so using the Group Policy editor. You can hide the Content Advisor options while leaving the feature enabled from the IE Internet Options menu.
