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!

即使在“显示来自所有用户的进程”上放置了复选标记，PID=4也不会显示在任务管理器中。只有一个用户。

但是，netstat -b显示指向同一PID=4的多个连接，在此计算机上显示如下所示。

我只选择了那些与TCP协议有关的。

这是在解决IIS的问题时获得的，IIS在尝试了许多其他人之后没有开始。我认为你不应该停止这个过程。

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

输入netstat -a -n -b -o |more

如果停止万维网出版服务有帮助的话

然后在IIS管理器中查看每个站点的绑定设置，通过选择一个站点并在侧面板上单击绑定。然后如果需要，将端口80更改为其他端口。

听起来好像IIS正在监听HTTP请求的80端口。

尝试通过进入控制面板/管理工具/Internet信息服务停止IIS，右键单击默认网站，然后单击弹出菜单中的停止选项，并查看端口80上的侦听器是否已清除。
