Block websites without using any softawres

We can block websites in windows by modifying HOSTS file.

What is HOSTS file?

One of the lesser known, but important files included with Windows is the hosts file.

It's a simple text file without any file extension that was designed to map or override IP addresses before accessing a domain name server.

i.e when you enter a domain name (eg:www.google.com), your browser searches for the IP address of www.google.com in your HOSTS file before searching it in the DNS server.

Procedure:

step 1)open your notepad with admin rights as shown below.

step2)now goto file and click on "open" and then navigate to C:\windows\system32\drivers\etc

step3)Now change your extension to "all files" in the notepad.

         you will see HOSTS file and open it.

It will look like 

step4)add the following lines in the HOSTS file as shown in the figure.

          127.0.0.1  www.google.com

           127.0.0.1    google.com

step5)save it. and open your browser. Now type www.google.com

        It will not be opened.
