How do I remove/forget wireless networks in Windows 7?
Follow the steps below to remove old Network Connections on your Windows 7 computer.
1) Use your mouse to click the Start menu and select the Control Panel.
2) Click the "Network and Internet" button once the Control Panel loads and select the Network and Sharing Center.
3) Click the "Manage network connections" tab.
4) Look for the old network connections you wish to remove in the scroll box. Depending on how many connections you currently have in Windows Vista it is possible you'll need to scroll a bit to find the one you wish to remove.
5) Click on the old connection you wish to remove.
6) Click the "Remove" button.
7) Confirm your selection by pressing "Yes" when asked whether you are sure you wish to remove the connection. You may also elect to press "Cancel" or "No" to return you to the previous screen and prevent the connection's removal.
8) Note that you can also change network connections through the network wizard. Simply click Start, then "Connect To" and "Show all connections."
9) Select the network connection you wish to change by right-clicking on it and selecting the option you wish. You can choose to "Disable" the connection, which would have roughly the same effect as completely removing it, rendering it inactive.
10)Press the "Delete" key after clicking on a network connection in the Network Connection window. This will completely delete the connection in the same way that removing it from the Control Panel would.
