How to change the port number in wamp server in windows

  Hello Mates...
                       Do you guys know how to change the port no of Wamp Server..

• First STOP all the services of wamp and exit from wamp if you are already using it..
• Follow the path

          +Wamp Root Folder

                 +bin

                     +apache

                            +apache2.2.22(changes based on version of apache using)

                                 +conf

Ex:  C:\wamp\bin\apache\apache2.2.22\conf 

• In the conf folder select and open with notepad "httpd.conf" file
• After Entering in the notepad use ctrl+F and search the file for 80 or word "Listen".

Change Listen value as shown

• Do not use the port no that belongs to os or some other software..
• Save the file and exit 
• Start the "wamp server" and start the services
• You can see  your "wamp" running in your assigned port no..
