I want to run MAMP on my Windows 8.1 pc, but when I start the servers, it says:
\'APACHE\' needs open port \'80\' which is already being used by another
service
Thru some web searches, I discovered that other windows services are know to be using Port 80. In Windows Search (via Windows Start), type 'services', stop one of these services below en test again till it works. Do not forget to restart it later !
