Do you want to block some websites in your PC but you want to do that without installing any software, then I’ll show you the trick to that. By blocking I mean that you can stop certain websites from opening on your PC. This can be due to any reason like you are a boss and don’t want to make your employees open orkut, facebook or any other which you think is not good.

Now follow these steps to do this:

1) Browse to C:\WINDOWS\system32\drivers\etc
2) Find the file named “HOSTS”
3) Now, open it in notepad
4) Under “127.0.0.1 localhost” Add 127.0.0.2 www.yourblockedsitename.com , and this site will no longer be accessable by anyone.
5)That’s it you are done.

The final look should be like this:

127.0.0.1 localhost
127.0.0.2 www.blockedsitename.com and then keep going adding one to the last digit here. Like if I wanna block one more site then I would write

127.0.0.3 www.newblockedsite.com .Ok, now you understood, so enjoy.
