I have just installed XAMPP and everything works fine except that I can\'t get apache to run. It seems that port 80 is the problem, I have disabled Skype to use port 80 but
Skype, try closing it and then running xampp, if it works then change the skype port to stop using port 80
There are 2 ways to solving this problem.
#Listen 0.0.0.0:80
#Listen [::]:80
Listen 80
by
#Listen 0.0.0.0:81
#Listen [::]:81
Listen 81

If you didn't find “World Wide Publishing Service” there then go to "Run>>resmon.exe>> Network Tab>>Listening Ports" and see which process is using port 80

And from "Overview>>CPU" just Right click on that process and click "End Process Tree". If that process is system that might be a critical issue.
just disable "world wide web publishing service" , it solve my problem.
Take a look at this site:
http://www.lukebrowning.com/blog/nt-kernel-system-using-port-80/
In my case, it was the SQL Server Reporting Service, but others have seen IIS or the Web Deployment Agent Service.
Open a cmd window and run services.msc, find the service, and stop it. Then try to start Apache. If it works, disable the other service.
I had the same kind of problems. I finally made it to work.
I successfully changed the apache ports to listen to ports not used by other programs Port 443 is used by SSL and Skype
I believe that the XAMPP Control Panel has a bug and I have screen shots in my posts to. I do not have enough credibility on this web site to upload pictures.
I have the whole thing written down with screen shots in the following blog posts:
