Teach you to remove the NIC local connection 2 tips

After a problem with the network card and reinstalling the network card driver, the system will automatically create a connection, and this connection will be changed from the original "local connection" to "local connection 2". And the information about "local connection" still exists in the system. When you set IP and other related information in "Local Area Connection 2", if these parameters are the same as those set in the previous "Local Area Connection", the system will prompt the information occupied by other network cards. At this time, you can manually Delete the previous connection information and convert "local connection 2" into "<local connection", the problem can be solved by opening the registry editor and expanding to

“HKEY_LOCAL_MCHINESYSTEMCurrentControlSetControl Network{ 4D36E972-E325-11CE-BFC1-08002BE10318}”, information about the local connection is saved under this subkey. There are one or more subkeys here, the first subkey corresponds to "local connection", the second subkey corresponds to "local connection 2", and so on, you can also expand the subkey, and then Select the “Connection” subkey below, and you will see which connection corresponds to the corresponding window in the right window, and delete the entire subkey corresponding to the previous old connection.
