Quickly delete the extra network connection in the win8 computer

1. First, we need to return to the traditional desktop location of the win8 computer. After that, we can press the win+R shortcut key on the win8 computer keyboard to open the running window of the computer. In the open run window, let's type regedit and click Enter. This will open the registry editor window of the win8 computer.
2. In the open Registry Editor window, click on the HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsNTCurrentVersionNetworkListSignaturesUnmanaged in the left menu.
3. After that, we can see a lot of sub-projects in this Unmanaged, where you can view the corresponding network connection, and then delete the corresponding items of the network connection that does not exist. Be careful not to delete the available network items, so it is best to back up the registry before the operation.
