Win 7 network mode lock problem

I don't know if Windows 7 users have encountered such a 尴尬—— want to change the location of the current network connection in the network and sharing center, but found that the corresponding location connection is not optional, so it is locked in the public Network mode, but can not be changed to home network or office network.
In fact, this is not something wrong with Windows 7, but the lack of design settings. If you have chosen a public network for a network connection and checked the option below, "I will treat all the networks I connect to in the future as a public network, and don't want me to ask", congratulations. The problem above is coming.
Obviously, this option for Windows 7 is for the convenience of the user, but once selected, it is difficult to go back: the network connection defaults to the shared network and can't open this dialog box, then naturally can't cancel This option is gone.
