Look at the top of your screenshot. "Managed by System Administrator" means there is a Group-Policy override. Since it is Ultimate, 1. just fire up Group Policy Editor (gpedit.msc), 2. navigate to Computer Configuration - Administrative Templates - Windows Components - Windows Update, 3. at the right side you now can access all GPOs regarding Windows Update. Accessing 'Enabled' or 'Disabled' settings and re-set to 'Not Configured' will restore the normal OS controls.
