With growing concern over the effect of online content on office productivity or young viewers, a number of homes and offices are implementing plans to block certain websites. YouTube, although the site also contains a wealth of high-quality and useful content, is one site often singled out for blocking, due to potentially inappropriate content. While a number of Web browser add-ons and software solutions can be used to block sites, the simplest and most cost-effective way to block a website on a Windows 8 machine is to edit the host file.
