There's a popup you can't close if someone connects to your machine, isn't that enough? Anyway, I was hoping there is something I'm missing, but if this is the way it should work, I guess I'll have to look into something more practical. Anyway, thank you for the answer and good luck.
How do I minimize/close to tray the RU agent? Having it opened in the taskbar is really counterproductive as you can accidentally close it when trying to close a different application. It also adds another "tab" when alt+tab-ing though opened applications and uses unnecessary space on the taskbar.
