itnaveen,
An easy way to find these is to open the Administrator console, select Package Management, select WmRoot, select Browse Services…
The list of displayed services are used both by the Admin console and behind the scenes.
Keepin mind these are undocumented, likely to change, and in many cases, the input/outputs are obscured to prevent easy “misuse”.
