Reason why some controls on the local connection properties page are disabled

Recently, when you open a network connection, a dialog box is often displayed when you view the Local Connection Properties: "Some controls on this property page are disabled because one or more network page properties have been opened.

Of course, this method does not necessarily apply to all situations, and some people on the Internet say that some problems have occurred after the IP helper service is stopped, but it solved my headache for a few days, do not care about others for the moment.
What is IP helper? This is an introduction to http://itsvista.com/2007/05/ip-helper /.

According to my understanding, when you use IPv6, the IP Helper Service can help you convert the address, protocol, and so on, so that you can access the IPv4 address, otherwise, you can only access IPv6 addresses. If you do not use IPv6, this service can be disabled.
There is also a small problem.

Finally, select "QoS Network Package scheduler.
Of course, there are still some problems. This service has always been started by default. Why is it so recently? Why is this problem not found on most hosts.
