In Windows 8, the network and sharing center removes the "Manage Wireless Networks" option. The network icon in the lower-right corner can only display the hot spots that can be found Currently. It is inconvenient to manage all the connected summary files. It can only be implemented by using commands.
First, Win + R Open "run", enter cmd, and enter the command prompt.
1. Display all wireless configuration files on the computer. At the command prompt, type:
Netsh wlan show profiles
2. The security key of a configuration file outside the specified range is displayed. At the command prompt, type:
Netsh wlan show profile name = "ProfileName" key = clear
3. Delete a configuration file out of the scope. At the command prompt, type:
Netsh wlan delete profile name = "ProfileName"
4. Stop automatically connecting to a network out of the range. At the command prompt, type:
Netsh wlan set profileparameter name = "ProfileName" connectionmode = manual
