This is my first time using this site. I asked for help with a problem and thought I would get a simple answer to resolve my problem that I understand. This is why I do not like social media
This forum is not some social medium. It is a vehicle created by Microsoft where a large number of people post their Windows problems. Many of them are solved by volunteers from the general Windows community. They are not MS employees and they get no compensation for the time they spend in trying to answer questions.
Your post is a little confusing. Intially you asked
Can someone tell me how to log off the Administrator.
You now ask this:
Is there anyone who could assist me in removing the Administrator icon off the welcome page.
That's two completely different things. Which one is it?
Also: Do you have two fully tested accounts with admin privileges? You must have two, same as you have at least two house keys. Why? Because you would be in diabolical trouble in case your single admin account goes bad for some reason. Happens all the time!
