Tray Service is a very basic utility, totally free, which alphabetically lists all the services and processes active at any moment in your PC.
From Tray Service you can add the processes to the list that you want, and, from there, minimize them to the taskbar. You can start them, stop them, restart them, pause them momentarily, etc.
This way, with Tray Service, you`ll have total control of each of the active services. It is, without doubt, a very basic and simple tool, but one which could be highly useful in certain moments, when you want a specific service.
