Block websites in your PC by modifying the windows....!!!!!

I guess this method is still unknown to many people....blocking websites is not a big deal.. but do neone knows how to block websites by modifying the windows...!!!
newaz i have found a way out...by adding juss 2 to 3 lines of code to the window file, you can block anyone to stop viewing that website on your system....!!!! juss concentrate on the method...!!!
you might or might not have heard about the HOSTS file in windows...
from now onwards you will consider HOSTS file as a master file for blocking websites....!!

1) Go to your HOSTS file which is located at:
C:\WINDOWS\SYSTEM32\DRIVERS\ETC for windows Vista and XP
C:\WINNT\SYSTEM32\DRIVERS\ETC for Windows 2k
C:\WINDOWS for Windows 98 and ME

2. Open HOSTS with Notepad.
The default Windows HOSTS looks like this:
______________________
# Copyright © 1993-1999 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a “#” symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
#
127.0.0.1 localhost

3) Directly under the last line that is 127.0.0.1 localhost, write the name of the website you want to block.
For example to block the myspace.com homepage, simply type:
127.0.0.1 myspace.com
127.0.0.1 http://www.myspace.com/
You need to write the URL of the website in both the ways...as suggested above...!!!
You can add as many sites as you wish to block in this fashion.

4) Save the file and close the notepad.

6) Just check the website by entering the address of the website in your Internet browser. You will find that the website can't be accessed...!!!!!

In some cases the reboot of the system is also required. So if you find that the website is still being accessed, just restart the system once and then try...!!!

In case of any queries, just mail me to get the solution...
