how to make iis 7 to stop using port 80?? Configure WampServer 2.0 on different (change port from 80 to 81)

I assume your server Configuration:
Apache Version: 2.2.
PHP Version: 5.2.6
Now that you have WampServer 2.0 installed, you'll want to use it along side with other servers such as IIS. This is easily done by changing the port that WampServer 2.0 listens to. I suggest changing the port from 80 to 81.
Use Notepad or WordPad to open the files below.
Open the httpd.conf file for the Apache server. On my machine, it's located here C:\wamp\bin\apache\apache2.2.8\conf\http

d.conf
Do a search for "Listen 80" and replace it with "Listen 81".
Save and close the file.
Open the wampmanager.tpl file. On my machine, it's located here: C:\wamp\wampmanager.tpl
Do a search for "http://localhost/" and replace it with "http://localhost:81/" (There are three total).
Do a search for "${w_testPort80}" and replace it with "${w_testPort81}".
Save and close the file.
Open the testPort.php file. On my machine, it's located here: C:\wamp\scripts\testPort.php
Do a search for "80" and replace it with "81" (There are three total).
Save and close the file.
Open the english.lang file. On my machine, it's located here: C:\wamp\lang\english.lang
Do a search for "$w_testPort80 = 'Test Port 80';" and replace it with "$w_testPort81 = 'Test Port 81';".
Save and close the file.
Right click on the WampServer icon and click on "Exit".
Restart your WampServer.
Congratulations! You have now changed your WampServer 2.0 to port 81. All of your links (localhost, phpMyAdmin, SQLiteManager) are configured to the new port and you can even test port 81 by going to the Apache Services.
after for php my admin config:-The configuration is stored in wampmanager.ini, located in the wamp installation directory.
This file is generated from wampmanager.tpl though, so you need to change the following line there:
Type: item; Caption: "${w_phpmyadmin}"; Action: run; FileName: "${c_navigator}"; Parameters: "http://localhost/phpmyadmin/"; Glyph: 5
