New ThinOS features
Admin Policy Tool
ThinOS 9.1 does not support FTP, HTTP, HTTPS file server, and INI parameter settings. You can configure these settings using
a local management tool called Admin Policy Tool. Wyse Management Suite and Admin Policy Tool user interfaces are identical.
However, Dell Technologies recommends that you use Wyse Management Suite to configure ThinOS 9.1.
NOTE:
After you reset the thin client to factory default settings, the device starts the First Boot Wizard application by
default. You can use the Admin Policy Tool to change the default settings for First Boot Wizard.
