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.
HI thanks but what i mean is auto complete not auto correct.
this is the feature which gives us option to choose the email address out of the available ones by the same name after entering just first few characters of the person's name or email id  in To, CC or BCC.  any suggestions how i can get this feature to work or reset, it was working fine when i was using outlook on my pervious mac book but after migrating all the data through time capsule to new one with retina, its not working
