   Navigate to the "etc" folder. To do so:

   • Click This PC on the left side of the File Explorer window.
   • Scroll down and double-click your hard drive's name (usually OS (C:)) in the middle of the window.
   • Double-click the "Windows" folder.
   • Scroll down and double-click the "System32" folder.
   • Scroll down and double-click the "drivers" folder.
   • Double-click the "etc" folder.

   • Right-click the "hosts" file.
   • Click Properties in the drop-down menu.
   • Click the Security tab.
   • Click Edit.

    Add websites to the block list. To block a website in your computer's browsers, do the following:

    • Type in 127.0.0.1 and press Tab ↹.
    • Type in a website's address without the "www" section (e.g., "facebook.com", "twitter.com").
    • Press ↵ Enter to start a new line, then repeat the above two steps with other addresses you want to block.
14. 
    14
    Block Google Chrome sites using this method. While you can block sites in most browsers using the above step, Google Chrome is slightly different: if you're blocking sites on Google Chrome, you'll need to place a space and then the "www.[site].com" version of the website's address after the "[site].com" version.^[3]

    • To block Facebook, for example, you would type in 127.0.0.1 facebook.com www.facebook.com.
    • Adding the "http://" or "https://" part of the address as well (e.g., 127.0.0.1 facebook.com https://www.facebook.com can improve the chances of the site being blocked.
15. 
    15
    Try blocking alternative versions of the website's address.

    • IP address — You can find a website's IP address and then block it in the "hosts" file to prevent people from accessing the website via its IP address.
    • Mobile site — By placing "m." in front of a website's address (e.g., "m.facebook.com" instead of "facebook.com"), you can block the mobile version of the website as well.
16. 
    16
    Replace the existing "hosts" file with the edited one. To do so:

    • Click File in the top-left corner of Notepad.
    • Click Save As... in the drop-down menu.
    • Click the "Save as type" drop-down box, then click All Files in the drop-down menu.
    • Click the "hosts" file in the main window to select it.
    • Click Save, then click Yes when prompted.
17. 
    17
    Flush your computer's DNS cache. You'll use Command Prompt to perform this action. Flushing the DNS cache will prevent saved browser information from clashing with your blocked sites.^[4]

    • Press the Windows key and type "cmd".
    • Right-click Command Prompt.
    • Click Run as administrator.
    • Click Yes to confirm.
    • In the Command Prompt, type ipconfig /flushdns.
    • Press Enter.
18. 
    18
    Restart all browsers. If you have any browser windows open, close them and then re-open them. Any websites you added to the "hosts" file should now be blocked in your browsers.

    • If the websites still aren't blocked after restarting your browsers, try restarting your computer.
