Hi Tom Blanco, I request you to reset the Internet explorer by following the steps below- (1) Open the Internet browser. (2) Click on the ‘tools’ option. (3) Select ‘internet options’ tab. (4) Click on the ‘advanced’ option. (5) Then, click the ‘reset’ option. If this doesn’t work request you to uninstall Internet Explorer 9 then reinstall it.
Internet Explorer 9 stopped retaining usernames and passwords for websites.  I have tried to reset the autocomplete settings several times and it would only last during a session.  I really liked the convenience of not having to type usernames and passwords for my favorite safe websites.  It think it happened after the conflict of McAfee with the Windows 7 update.  That conflict caused not being able to connect to the web.  As recommended I uninstalled and reinstalled McAfee to fix the problem.  I can not find other solutions from the web.
