ServiceTray is a free tool which is able to start, stop, restart and generally monitor any single Windows service from your system tray.
A clear and simple setup dialog allows you to choose the service to be monitored, and your preferred system tray icon. If you'd like the program to be running all the time, a shortcut can be added to your Startup folder. Otherwise it generates a shortcut on the desktop, where you launch it as required.
Once active, ServiceTray keeps you up-to-date by displaying alerts if your service starts or stops unexpectedly. Its icon colour also indicates the service's state: green means running, red means stopped, and yellow means it's somewhere in between (starting or stopping, usually).
Double-clicking the icon displays a more detailed report, including the service process ID, session, CPU and RAM usage, start and up time.
Right-clicking the ServiceTray icon displays the usual Start, Stop and Restart options. A "Switch to Session 0" feature may display messages from interactive services, and there are shortcuts to some related Control Panel applets (Services, Task Manager, Event Viewer).
