Although this is not a rocket science, this is by no means any attempt to break into a locked Wifi network and recover its password. You can always view the password for your currently connected Wifi network. Here is how to do it in Windows 8:
1. Click the connected wifi network icon in the bottom right corner of your screen
2. Now Right click the connected network and click View connection properties
3. When you check Show characters, it would show the password of the currently connected network.
