How to Block YouTube

By Edward Mercer

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.

Make Host Files Editable

Step 1

Log into Windows 8 as an administrator and launch the Start Screen.

Step 2

Type "Windows Defender" into the search field and click on the application icon.

Step 3

Click on the "Settings" tab on the right and select Excluded Files and Locations from the menu on the left.

Step 4

Click on the "Browse" button at the top and navigate to the C:\Windows\System32\Drivers\etc directory. If Windows is installed on a drive other than C:, find the directory on the drive where you installed Windows.

Step 5

Select the "hosts" file in the "Etc." folder and click on the "OK" button.

Step 6

Click on the "Add" button in the main Windows Defender screen to exclude the file from Windows Defender protection.

Step 7

Click on the "Save Changes" button and close Windows Defender.

Block YouTube

Step 1

Launch the Windows Start Screen and type "Notepad" into the search field.

Step 2

Right-click on the Notepad app and select "Run as Administrator" from the options on the bottom of the screen.

Step 3

Click on the "File" tab in Notepad and select Open.

Step 4

Navigate to and open the hosts file from the directory C:\Windows\System32\Drivers\etc.

Step 5

Scroll to the bottom of the document and type in "127.0.0.1 youtube.com" to block YouTube.

Step 6

Save the changes to the file and close Notepad.

Tips & Warnings

  • You can use the same code to block any website. To block Facebook, for example, enter "127.0.0.1 facebook.com" into the bottom of the host document and save your changes.
  • Any website you block in the file will become inaccessible from all Web browsers on your computer.
