I recently switched my account to local account, and have the Users must enter a user name and password to use this computer UNCHECKED. but now whenever i turn on my computer i get an error saying wrong password, and i have to type in my password. and for some reason it shows that i have two different accounts one which is my local and another one that i don't ever remember creating but has a user name i also use. but also when i go to User Accounts i only have the local account
