In the process of using Windows 8, it is sometimes repeated to add a network connection, although it does not affect normal use, but a long string of useless connections looks very uncomfortable. In addition, some default network names (such as "Network 2") are neither intuitive nor pleasant to hear. However, these connections are not directly deleted and renamed, we can only use the registry to complete.
Click the Network icon in the system tray area to view the network connections currently in use, such as ZJGGMXX-JWC2, under the list of available networks. Then press Win+r key to pull up the Run dialog, enter regedit and press ENTER, open Registry Editor, and then jump to HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows Ntcurrentversionnetworklistsignaturesunmanaged, under which there are subkeys, where you can view the appropriate network connections, and then delete the entries for network connections that no longer exist. Note that you should never delete the available network entry (this example is ZJGGMXX-JWC2), so it is a good idea to back up the registry before doing so.
Next, you can rename the network connection name you are using, in this case, double hit open zjggmxx-jwc2 in the description, enter the name of the network connection you want it. When the system is restarted, the changes take effect, and friends who need it can try.
