How to remove user password on windows 8.1

Ok I have a problem. Many of you may not consider it a problem but it is for me.

I had my new Windows 8 laptop for 6 months now. The useame that i use for it did not have a password. I am ok with it. But today I decided to try Windows store for the first time. It made me make an account and all. Bad experience! It forced OneDrive upon me. I got a temporary solution for it. But something that I did not notice on the spot was that my useame kinda changed and its like the account that i made got attached to it or something; the email gets displayed below my useame. Now everytime I have to put my password before logging into the system.

I do not want to delete my current account as all my data and settings are in this user's folders.

I want it back to the way it was before. Can someone help?
