In case a security warning appears upon connecting to the machine through RDP, requiring re-entering the user's credentials, hence creating an issue with the auto-login functionality of WinAutomation or ProcessRobot Solobots, one way to bypass it is by navigating to the Local Group Policy Editor > Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Security and disabling the "Always prompt for password upon connection" setting.
