I have just upgraded to Internet Explorer 10 and when I sign in to my Hotmail I have to type in the entire address each time. There are 4 family members using the same computer so I don't want it to keep me signed in. I just want to type in the first letter and have it fill it in for me like it did yesterday when I was on IE 9.  I have gone to the internet options and made sure all of the auto complete buttons are turned on.
