Change who has administrative privileges
Administrative privileges are a way of deciding who can make changes to important parts of the system. You can change which users have administrative privileges and which ones don't. They are a good way of keeping your system secure and preventing potentially damaging unauthorized changes.
You needto change account types.
Type "Settings" into the global search bar on your desktop. Click on the resulting Settings icon, or press Enter, to open.
Click on Users.
Press Unlock in the top right corner and type in your password when prompted.
Select the user whose privileges you want to change.
Click the label Standard next to Account Type and select Administrator.
The user's privileges will be changed when they next log in.
The first user account on the system is usually the one that has administrator privileges. This is the user account that was created when you first installed the system.
It is unwise to have too many users with Administrator privileges on one system.
