URLFilterService is a free internet filter application for Microsoft Windows operating systems.  It natively filters requests  in Microsoft Edge and Internet Explorer but any other  application is supported, locally and remotely,  via its DNS sinkhole server function. It works completely on your computer and  no data is sent outside your network except allowed request for dns name resolution. UFS  works both with ipv4 and ipv6 addresses, any external DNS resolver and any kind of device (tablets, phones, smart-tv, game systems, etc). Please note: to work properly you must allow private and public network communications in your antivirus and/or firewall to urlfilterservice.exe.

It can be used to build a  personal trusted list of internet sites helping you to avoid unwanted web content of any kind. Unlike other internet filters UFS integrates a default/deny option, giving you a chance to resolve hosts only if they are already present in a known category removing the need to constantly check for newly created domains.
