To solve this problem, you can search the Internet for many solutions and try them one by one.
1. Some say that IIS is re-installed (I have re-installed, but it still cannot be started)
2. Some say that the EventLog service can be enabled before the World Wide Web Publishing can be enabled (I tried it, but I still cannot do it)
3. Some say it is good to delete the kb939373 patch (this patch is not found)
4. Some users say that it is good to delete the kb2290570 patch. (although the patch has been installed in patch 360, the patch location cannot be unmounted)
5. Finally, if you uninstall the kb2290570 patch, find it. If you have deleted the patch backup directory in windows, You Cannot uninstall the kb2290570.
