This is a great way that you can reveal the saved WiFi passswords on a Windows system using CMD. This is handy if you want to connect another computer to the network or share with a friend that wants to connect.
First load up CMD (As an Administrator)
Type in CMD netsh wlan show profiles
and press enter:
The next step is note the WiFi access point that you want to show the password for, in this example we will use Magnums Public an the use this command:
netsh wlan show profile "Magnums Public" key=clear
