Anyone knows how and where the WiFi passwords are stored in windows-7. i want to saving and restoring when if you forget your username or password.
In the past, I've used NirSoft's WirelessKeyView to get my saved wifi passwords. It's free and works well. Be sure you download the correct version (32 or 64 bit).
Go to Control Panel\Network and Internet\Manage Wireless Networks, select network profile from the list, right-click > choose Properties > switch to Security Tab > check the "Show characters" check-box.
