How to release port 80

Few days ago, I fall in a problem. I could not start apache server by XAMP control panel. There was a message shown port 80 busy. However ultimately, I found the solution this was due to IIS server. IIS Server was running on port 80 at that time.

Here is the step by step procedure, how I release port 80

1. Go to command prompt.
2. Check which process is using port 80
   • On the command prompt window, type the following command.

     netstat -o -n -a | findstr 0.0:80
     

   • You will see the following screen

2. Go to the Processes tab.
3. Click the View menu
