Deleted administrator account

I am getting annoyed by getting asking for my password when i download applications it happened after i deleted my first account. I need help so i can either turn off that option and i did already turn it down once because that is all it would let me without the "administrator account" Please Help!!

Sorry to tell you there is nothing you can do to fix it without an admin account all you can do is learn from it to never deleate all admin accounts on a PC
