Hello Rafael,
Thank you for your message.
Could you please clarify if you mean hiding the Host icon from the system tray? If this is the case, hiding the Host icon from the system tray is not possible for security reasons. We discontinued this feature since
version 6.3.0.4.
However, if you don’t want the remote user to stop or restart the Host, enable the
Hide Stop Host and Restart Host menu items option in the
Host settings, on the
Interface tab:

You can also learn more about Host Settings here:
