I installed a new printer on my computer this week and it has changed the way my computer is operating.Before installing the printer my computer was running great.I could start my computer

and it would boot all the way up and ready to use.Now it stops and wants me to click on a user account.I am the only one who uses this computer .How do I get this operating the way it did before?How do I get around this user account thing.There must be a way because it worked fine before without it.Thank You!
