How to Change a Network Key in Windows 7
One nice aspect of the way that Windows 7 manages networks is that you can access a list of networks to which you have connected through the Control Panel. So even if you are not currently connected to a network for which you need to change the security settings, you can make adjustments as you find out about them. This level of control will help to ensure that you have the ability to stay connected to networks at home, work or on the road.
Step 1: Right-click the network icon in the system tray at the bottom-right corner of your screen, then click the Open Network and Sharing Center option. If you can not find this icon, you can also access the Network and Sharing Center menu from the Control Panel on your Start menu.
