So I have faced the same problem when trying to start apache service and I would like to share my solutions with you.
Here is some notes about services or programs that may use port 80:
- Skype: skype uses port 80/443 by default. You can change this from tools->options->
advanced->connections and disable checkbox "use port 80 and 443 for addtional incoming connections".
- IIS: IIS uses port 80 be default so you need to shut down it. You can use the following two commands
net stop w3svc
net stop iisadmin
- SQL Server Reporting Service: You need to stop this service because it may take port 80 if IIS is not running. Go to local services and stop it.
These options work great with me and I can start apache service without errors.
The other option is to change apache listen port from httpd.conf and set another port number.
Hope this solution helps anyone who face the same problem again.
