If you forgot your wireless password for your current or saved Wi-Fi, connection, then it's very easy to find it for any one of your saved connections using either the GUI or command line in Windows. If you need to find the password for a connection you are not currently connected to then you will need to use the netsh wlan command.
Here are the commands. Just be sure to remove the quotes from the SSID name.
netsh wlan show profile
netsh wlan show profile "Your SSID" key=clear
#wi-fi
#wireless
#networking
