Open the "Control Panel" on your Windows computer.
Click on "Network and Sharing Center."
Click on the Wi-Fi network that you want to see the password for.
Click on the "Wireless Properties" button.
Click on the "Security" tab.
Check the "Show characters" box next to the "Network security key" field.
This will display the Wi-Fi password in plaintext so that you can see it. Keep in mind that you may need administrative privileges on your computer to view this information.
