There are times you may need to recover the Wifi passwords stored in your Windows workstation. Maybe you don't remember what the password is on a network, or maybe your are moving computers, etc. To find it, you need to open an administrative command prompt and run the following command:
netsh wlan show profile
You will then be shown a list of all the Wifi networks stored on your computer. Note the name of the Wifi network you want to get the password from and enter the following command (NOTE: We will use Test Wifi as the name in this sample:
netsh wlan show profile "Test Wifi" key=clear
It will then display information on the Wifi network, and under the section for "Security settings" you will find the "Key Content" which will contain the password for that Wifi network.
