There is only really one thing you need to remember: you need to be connected to the network for which you want to retrieve a password.
Use the following steps:
- Press the Windows key and R at the same time, and then type ncpa.cpl and press Enter.
- In the Network Connections Control Panel that appears, double click on the icon for the wireless network adaptor.
- Click the Wireless Properties button and then move to the Security
- Check the Show characters box to display the password. (You may need to confirm this via a User Account Control dialog.)
