I am the only one who uses my PC. Therefore, I don't need passwords or anything else when I restart. I used to just see the Welcome Screen, and nothing else. Now I've somehow managed to complicate things after utilizing Autoruns. I would really appreciate it if someone could show me how to get back to the simplest possible restart. Also, at the same time, I would like to ensure I have administrative privileges. Recently, I have been denied access to a couple of applications for that reason.
Thanks for your help.
