WIN7 IIS Default Web Site cannot start, prompting another program to use, exception from hresult:0x80070020 solution

Just entered the new company, because the last technician using IIS to build a station, I used the Apache build station so on the original based on the addition of Apache, but know that the server reboot will automatically start Apache, which will occupy 80 of ports to use the IIS Web site 80 ports are not available

Tip: Another program is in use and the exception is from hresult:0x80070020

Solution: 1. See if 80 ports are occupied
Netstat-ano View 80 port occupancy. Win+r Enter the CDM entry and continue to enter "" Netstat-ano "(-before a space)

Find 80 after looking at the back of the PID number, this is 4

Open Task Manager to see if the PID number is 4, some words to see if it's Apache, yes, it's forbidden to start.

Now it's no problem to open the IIS startup Web site.
