How to select a check box in Windows 7

[flipside82 0]

I am working on putting together and AutoIt script that will setup the AutoLogin feature for Windows 7. Here are the steps I want to do: Open the User Accounts window, Check a check box, Select a username from the list, Uncheck the check box, Click the OK button, enter a password twice in the box that pops up and then close the windows. So far all I have is opening the User Accounts window. I am accomplishing this with: Run("control userpasswords2","c:\windows\system32"). Now I'm stuck on what to do next to check the check box and so on. I am new to AutoIt and really appreciate any help and suggestions you can offer. Thanks.

I have attached a screenshot of the User Accounts window. The check box above the user names is the one I need to check. Thanks again.

The ControlCommand() might be of some use here.
