Changes are coming to the way that you sign into MSN Explorer. In order to better protect your account from malicious activity, Microsoft is updating the way that you sign into our services. Your MSN Welcome screen will look the same until you click on your user name. At that point, you will see a sign in screen that looks more like a web page. As with all new Microsoft Account screens, you will no longer have the option to save your password.
The FAQ for the changes can be found by following the link https://membercenter.msn.com/SignupChangeFAQ.aspx
