Masalah Apache Port 80 [SOLVED]

Checklist yang harus dilakukan ketika Port 80 sedang sibuk/ga jalan. Biasanya disertai dengan kata-kata seperti ini: Port 80 in use by "Unable to open process" with PID 4!
Apache WILL NOT start without the configured ports free dan seterusnya..

F*ck you too Apache

- Stop IIS
- Run services.msc, terus Stop (Klik kanan, pilih Stop):
-> Web Deployment Agent
-> World Wide Web Publishing Service
-> SQL Server Reporting Services
- Buka task manager -> End Task python.exe
- Buka Skype, uncheck "gunakan port 80". Atau tutup saja skypenya di Task Manager

Update: World Wide Web Publishing Services, berhasil di Windows 8
