Changed only user account to owner

So, I think I just broke my new XPS 8950. I was going through installing things and I got a message that I needed to be an admin to do what ever it was that I was trying to do. I searched the internet and found a page saying to type in NETPLWIZ or something like that and I will be able to make changes. That is when I saw a setting that said "owner". I thought "hey, I'm the owner. That should be me". So I changed it......my only user account. Turns out it was a terrible mistake, I can't change it back. I cannot run anything that requires admin privileges, cannot uninstall anything that requires admin privileges, I cant even get into windows restore, safe mode or do anything to use the default admin privileges. I cant run powershell or command prompt as admin either. I have scoured the internet and have found a few other people that seem to be as bright as me and did the same thing, but nobody seems to have a solution. If there is anybody that has any idea how to fix this, please let me know....with detailed instructions...think of it like trying to teach a cave man rocket science....Anyways thank you to anyone that can help or tries to help.
