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!

BranchCache是我的问题。我的决心是以管理员的身份运行Powershell，然后运行:

Disable-BC -Force

参考:https://learn.microsoft.com/en-us/powershell/module/branchcache/disable-bc?view=win10-ps

尝试netstat -b，这可能会对情况有所帮助(显示什么.exe正在使用端口)。祝你好运。

IP地址为0.0.0.0,state = LISTENING:表示80端口正在监听所有接口(未被使用)

如何读取NETSTAT -AN结果:

我发现“SQL Server Reporting Services (MSSQLSERVER)”自动启动并在端口80上监听。

我希望这能有所帮助。

这对我来说很管用:

右键单击我的电脑。 选择管理。 双击“服务和应用程序”。 然后双击Services。 右击“万维网出版服务”。 选择停止。
