When I go to the initial login screen I type the first letter of my address. The address appears and I highlight it then go to the password and type it in and off I go. However an old email address beginning with the same letter also appears. I find this very irritating and I want to get rid of it.

Things I have done to try to get rid of it:

1. Clearing cookies.
2. Un-install Windows Live Sign-in
3. Right click offending email address
4. Examined regedit to see if it is in there.

None of these has made the slightest difference. Any suggestions?
