It’s a simple technique.

The user just needs to modify one “Host” file.

The user who is going to modify “HOST” file should have administrative privileges

1.] Browse C:\WINDOWS\system32\drivers\etc

2.] Find the file named “HOSTS”

3.] Open it in notepad

4.] Under “127.0.0.1 localhost” add 127.0.0.2 www.sitenameyouwanttoblock.com , and that site will

no longer be accessible.

5.] Done!

-So-

127.0.0.1   localhost

127.0.0.2 www.blockedsite.com

–> www.blockedsite.com is now inaccessible

The host file will have the following line 127.0.0.1 local host (it will be there by default) in all three operating systems windows XP, Windows Vista and Windows 7.

In the next line, we have to add 127.0.0.2 www.blockedsite.com,  127.0.0.3 www.abc.com

127.0.0.1   localhost

127.0.0.2 www.blockedsite.com

127.0.0.3 www.abc.com

127.0.0.4 www.xyz.com

Above example is for Windows XP.

In the Windows Vista and in the Windows 7 we have to add websites without #.

Example shown in Windows 7 image given below.

I have pasted host file to show how it looks in Windows XP, Windows Vista and in Windows 7 operating systems:

Windows XP Host File is shown below:

Windows Vista Host file is shown below:

Windows 7 Host File is shown below:

The users will be able to browse other sites; they would not be able to browse the sites which are all added in the host file.
