Do you mean that you want to minimize the Agent window to the system tray, correct? If this is the case, then unfortunately, minimizing the Agent window to the system tray is not possible. The Agent is supposed to work explicitly, that is, it should be always visible in the taskbar. If we add a tray-only option the remote user may easily overlook the fact that the Agent is running on their PC. Sorry if this makes Remote Utilities less useful for you.
However, you can easily minimize the Agent window to the taskbar or, use Host instead - Host is a persistent module and requires installation as well as admin privileges, but its icon is only displayed in the system tray.
Of course, it's possible to start Agent minimized to a taskbar. Here's how you can do it: 1. Right-click on your Agent package and select Create shortcut. 2. Right-click on the created shortcut and select Properties. Navigate to the Shortcut tab and in the Run section select Minimized. You can place this shortcut on your desktop and run Agent via the shortcut - this way it should always start already minimized to the taskbar. Please note that when running Agent, it's only minimized to a taskbar if you select No on the UAC prompt, i.e. if you run Agent as a regular user without admin rights.
