DWQA QuestionsCategory: ServerHow to close the default port 80 after IIS is enabled in win7?
agui1989 asked 1 month ago

I found that as long as IIS is enabled, even if the IIS service is not started, port 80 is also occupied. What’s the matter?
The website of IIS has two ports which are not 80. In addition, IIS is not started.
But port 80 is occupied by the system process with PID 4. Why?
Is there any other solution besides shutting down IIS?

Open the registry:
Change the actual start value to 0.

This problem can be caused by installing SQL server and opening IIS service again.
