We are connecting laptops running Windows 7 Professional to wireless access points which, for security reasons, automatically regenerate a new wifi key every time they are powered off/on (which happens frequently). I understand that I can uncheck the "connect automatically" box when connecting to the network and this will keep the password from being stored but I am looking for a way to have that box be unchecked as the default value so that the user won't have to manually uncheck it every time. We have several different types of laptops purchased across a number of years, is there a universal way that I can disable that check box?

--edit--

It would actually be preferable if there were a way to automatically "forget" the password on disconnect but still attempting to connect to the network automatically and simply prompting for the password.

You can follow the instructions in this SuperUser thread to set an automated task to trigger on network disconnection.

You can have the triggered task call a batch file with the following command:

netsh wlan set profileparameter name=<NAME OF WIRELESS CONNECTION> keyMaterial=SOMEunGues7123Able^&@Value

You can find the name of the wireless network with the command netsh wlan show profiles. In this approach, a blank password is not allowed so I have set an unguessable password. The next time the user connects, it will generate a password error and prompt them to enter the correct password.

As an alternative approach, you could simply delete the whole profile on disconnection with the command: netsh wlan delete profile name=<NAME OF WIRELESS CONNECTION>. That matches your first option, but not your "forget" option, for which the former seems to be the most practical way.
