User Account Control and Administrator Password

I installed Windows 8.1. I can sign on without using an administrator password. However, to open documents I get the User Account Control asking me to enter an administrator password. I didn't get this with Windows 7. For instance, when I go to Windows Update and I want to right click on optional downloads to hide the update, I get the User Account Control box asking for the password. Is there any way to delete or disable the Administrator Password function in Windows 8? Thanks in advance.
