As a result, I was delighted to find that Microsoft support exists. When I ran it happily, I was told what might happen.ProgramPort 80 conflicts with IIS. This answer is not concise. Check it again. Oh, someone is just like me. It turns out to be Skype !!! Its standby ports are 80 and 443. You don't know how to design them. Just remove the check box and go to connections in Skype --> Tools --> options.
