I have been using Windows XP Professional Edition. I have enabled to auto logon option in registry two three months ago. It has been working fine. But when I reboot my computer today it wouldn’t automatically logon. It asked to click the user name but there are not seems any username and password click option during the booting. There has nothing to seen where we click our username and put the password. What is the problem? How can it be solved? I have tired to open in safe mode but same thing repeat in safe mode also? I am in trouble? Please help me???
