Log on and admin

[Rekusu]

What one and all,

Again, some more W8.1 questions!!! Appreciate the advice as I frequently cannot find an answer on Dr. Google.

1. HP all in one, have removed most of the bloatware and want the computer to boot to the desktop. At some stage, I entered a Greeting Message as a welcome when my wife fires it up.

But.... the greeting appears and have to hit OK. Don't want to hit anything, just a few seconds of the message and move on automatically.

2. the next screen is a log-on. Have to enter a Username and enter. Have managed to by-pass the password but again, don't want this. Just want to go straight to the desktop.

Have been into Netplwiz and checked the box, but it still appears.

Also done the Desktop/right click taskbar properties / navigation and checked start to desktop but not effective.

How can I boot to the desktop immediately?

Admin.

I don't want W8.1 automatically installing updates. Have been to the System/Update but whatever option I select, I am told that I need admin privileges and cannot change anything. If I go to User, there are three accounts; Admin (with admin rights) / Momiji/Admin (with admin right) / Homegroup (with admin rights and I don't even know what it is)

As User shows all accounts with admin rights, why does changing the updates prevent me doing so and tell me that I need admin rights? How do I get around this?

Thanks very much.
