How to Block Websites in Windows (No Programs Needed)

How to block websites in Windows without using third-party programs:

Open the Start menu.
Search for Notepad.
Right-click and select Run as administrator.
File > Open...
Navigate to C:\Windows\System32\drivers\etc\.
Switch the file type to All Files (*.*).
Open the file called hosts.
Begin a new line below the '#' section. Start the line with: 127.0.0.1
Add one space and then type the domain without http:// or www. For example: website.com
The final entry should look like this: 127.0.0.1 website.com
Save the file.
Open a web browser and go to the blocked website. It should display a connection error and therefore be "blocked".
