这些对我都没用。我不得不回答一个超级用户的问题。

If it is a System Process—PID 4—you need to disable the HTTP.sys driver which is started on demand by another service, such as Windows Remote Management or Print Spooler on Windows 7 or 2008. There is two ways to disable it but the first one is safer: Go to device manager, select “show hidden devices” from menu/view, go to “Non-Plug and Play Driver”/HTTP, double click it to disable it (or set it to manual, some services depended on it). Reboot and use netstat -nao | find ":80" to check if 80 is still used.

这招对我很管用!

Netsh HTTP Show Urlacl

这个命令在前面的评论中提到过，但我想把它作为一个答案。它将为您提供系统中所有保留的url。如果您查看URL中所有带有“80”的记录，您就会得到您的答案。

例如，在我的例子中，我得到:

Reserved URL: http://+:80/Temporary_Listen_Addresses/
        User: \Everyone
            Listen: Yes
            Delegate: No
            SDDL: D:(A;;GX;;;WD)

Reserved URL: http://+:80/0131501b-d67f-491b-9a40-c4bf27bcb4d4/
        User: NT AUTHORITY\NETWORK SERVICE
            Listen: Yes
            Delegate: No
            SDDL: D:(A;;GX;;;NS)

在快速谷歌搜索后，我了解到“NT AUTHORITY\NETWORK SERVICE”属于SQL Server。所以我去了服务，停止SQL Server报告服务，端口80是空闲的，因为我检查netstat -a -b

我也有同样的问题。可以通过停止正在运行的服务下的万维网发布服务来修复它。

这不能解释PID方面的事情，但如果你运行Skype，它喜欢使用端口80出于某种原因。

在windows的最新版本中，这项服务被称为“万维网发布服务”(W3SVC)。

C:\Windows\system32\svchost.exe -k iissvcs

您可以通过进入Services (Services .msc)并停止该服务，然后设置“启动类型”—>禁用，以防止它在windows启动时运行。
