If you do not want to install any additional software, find the password in the Windows Command Prompt. Open the Start menu, search for "Command Prompt" and right-click on it to run as Administrator. Then run the following command to display a list of the saved Wi-Fi networks:
netsh wlan show profile
Select the desired network from the list and do the following :
wlan View Profile MyNetwork key = clear
(Replace MyNetwork with the name of the previously found network.) You will see some information about the network, including the "key content" or password. [1
