Change settings need to be system administrator

[Terry]

I’m trying to change the settings on automatic updates to download and
install, the settings screen will not allow me to change the existing
settings. Says it must be done by a system administrator. The machine is not
on a domain

I have administrator rights, but I’m not logged on as the administrator.

How can I change this and or how do I log on as the administrator.

Thanks

Yes, I'm logged as an administrator, but not "THE ADMINISTRATOR" Logging in
now I have all rights.
