HOSTEdit - an all in one tool for handling HOSTS files
Website - ScreenShot - Freeware
If you don't know what the Windows HOSTS file is then you may be missing an opportunity to block ads, cookies, and entire websites that you don't like. If you use the HOSTS file, then this is a tool you should try. It's like a swiss army knife for working with large HOSTS files. The download is small and all you have to do is unzip the download and run it. This is a tool that might be good for a portable troubleshooting kit.
