Here I am showing how you can configure IIS and WAMP server at the same time in Windows 10 or 8.
WAMP you can download and install from HERE.
IIS is preinstall on Windows 8 and 10, you need to enable it. You can refer to my step by step blog "Enable IIS (Internet Information Services) Server on windows 10" to enable it windows system.
You can not run both services at a time as they are using the same port. So keep it simple you just need to change port for Apache or IIS.
If you want to change IIS port you can refer to my Blog.
Follow below steps to change Apache port:
1) Open "httpd.conf" file located in folder "C:\wamp64\bin\apache\apache2.4.23\conf". You can also open file directly from system try if your wamp is running like below:
2) Search for "listen" text in file and update the default port 80 to 8080.
3) Now Restart the WAMP server to make new port number effective.
4) Open the browser with url "http://localhost:8080/" wamp will show home page.
Now Both server will work simultaneously.
If you wish to change IIS server port you can also do that. Refer to my BLOG.
