remove other user boot straight to windows

Windows Home Premium 7 64 bit

I used to boot up with no username or password to click, Now i have to click my admin user even though there is no password. In trying to fix it, i am not sure how, but i made an account with other user. I now have to choose between my admin and the other user and click the admin arrow even though it needs no password. I cancelled password in the bios but still get prompt.

Guest user is disabled. UpdatusUser refers to nvidia .I want it so there is just one user and it does not ask for the non existing password

I want rid of the other user and to boot straight to windows. I do not want to do system restore as last point is a week ago

Password in BIOS is completely other story than Windows Password.

Log in on your account.
Go to Control Panel\All Control Panel Items\User Accounts\Manage Accounts - Manage another - select account you want to delete and delete account and files till you only have your account and Guess turned off.

Report if you can boot strait as some MS services require to have a password.

OK what is BIOS password for

There is only guest under manage another

Thanks

I fixed it. First I went to start netplwiz and opened user accounts. i ticked "users must enter username and password to use this computer". I highlighted my username and went to control alt delete to create a new password which i left blank. That got rid of the other user but i still had a prompt for my username at logon

Then i went back to user accounts,highlighted my account and unticked "users must enter username and password to use this computer" and clicked apply- or maybe OK- A box opened with my username and i just clicked OK without entering any password.

Now I boot straight to windows with no prompt
