I have upgraded my laptop from Windows 7 Professional to Windows 8 Professional. Everything seems working fine but, I am seeing duplicate user ids in login screen. I used to have two user ids created earlier. After upgrade I am seeing 4 user ids (two for each of the original users). I have removed one of the user id that I am no longer using. Then both the ids for that user disappeared from the login screen with remaining two left.
Please help me in removing the duplicate user id, even though functionally there is no issue, but it is just annoying.
