Blocking sites on a Computer
Blocking access to a website on one machine can be easy, if only you block it on your complete operating system. So, all the Internet browsers would not be able to open that blocked website if this following method is used.
This method will work with all the Windows versions, we tested it on XP, Vista, 7, 8 and 10. The internet works by converting IP address to a particular name like Google.com gets translated from 184.108.40.206 (for example) this conversion system is called the DNS. So, you use some DNS server for opening any website, our computer has something that’s similar called a HOSTS file that store such data locally. By modifying it, you can disable access to any site in a matter of few seconds.
1. With an administrator account open the location / folder : C:\Windows\System32\drivers\etc\
2. Open the file named ‘hosts’ in a notepad, the last lines in the host file will look like :
# 127.0.0.1 localhost
# ::1 localhost
– a) If you are unable to open the host file, then right-click on file names as hosts and select properties. On Security tab, you need to select administrator account and click Edit.
– b) When a pop-ups, go on selecting the account again and check the ‘full control’ option. Click > Yes and then click OK on all pop-ups.
3. At bottom of the file, adding any addresses of a website will block it. To elaborate you need to add a new line at the end of the file that contains 127.0.0.1 and then the web address of the site you want to block, now opening that website will redirect to your local computer.
4. To block a website like for example – Yahoo.com add
& to block google.com add
you can add more sites, each in a new line and the sites will be blocked on every browser on your Windows PC.
5. Add all those websites you want to block and repeat this step until you are done.
6. Now close the hosts file and click Save. Reboot your computer for the changes to take effect and you’ll find that all those websites are now blocked.
6. By closing the hosts file and saving it will not block the sites, you need to reboot your machine and after the reboot all of those sites will be blocked.
