Make Windows forget a network connection password?

Solution 1:

To delete wireless networks in Windows Vista, go to Control Panel, Network and Sharing Center, under Tasks click Manage Wireless Networks.

Delete the networks you don't want to be stored (right click -> Remove Network).

I don't want it so that I can simply reconnect without having to input the password.

The next time you connect to a wireless network, simply clear the box Save this network, and the details will not be stored.

Solution 2:

Run "Credential Manager" (Start > type its name and choose in the filtered list ( for vista, 7)). Remove the corresponding credentials you need from the credentials list. Or Control Panel -> User Accounts -> Manage Your Credentials. Or Control Panel -> Credential Manager.
