Administrator Account
By default, the User account is automatically logged in. To bypass this, you can
hold <Shift> during the boot process or hold <Shift> and click Log Off, which
can be seen by selecting the right arrow next to the Shut Down button option.
NOTE: The default password for the Administrator account is Administrator (case
sensitive).
Logging into the Administrator account should be very similar to the User account, with
some additional icons on the desktop. Unlike the User account(s), the Administrator
account can:

Install and uninstall hardware and software.

Create and delete user accounts on the terminal.

Create account passwords for user accounts on the terminal.

Change names, pictures, and passwords.

Change a user's account type to administrator account.
NOTE: The Administrator account cannot change its own account type to a limited User
account type unless there is at least one other account with administrator-privileges on
the thin client. This ensures that there is always at least one administrator-level account
on the thin client.
