How to find your WiFi password in Windows 10
If you are not sure what your WiFi/wireless password is for the network you are currently connected to, that can be found directly within Windows settings.
NOTE: This would not allow you to get password information for networks which you do not already have the password for.
Here is how to locate the WiFi password in Windows 10:
Press the Windows Key and R on your keyboard at the
same time to open the Run box. Type ncpa.cpl
and click OK.
Right-click on the wireless network adapter - it will either list "Wi-Fi" or "Wireless" and click on Status.
Click on the Wireless Properties option.
4. Click on the Security tab, then click on the Show Characters check box to
reveal the WiFi password.
