Basically, RDM + Remote Desktop can activate a new channel of communication between the two systems. In this way, you can interact with the Windows desktop, from your phone, starting or stopping services, viewing system resources, restarting or shutting down the machine remotely, among other possibilities.
To enable the connection, the program uses a BES meeting, BIS, TCP / IP or http. It supports password access, includes a system of encryption to protect transfers and has a number of options for rapid mapping functions on the keys of your device.
This software doesn't give you access to all the apps on your computer but ultimately, if you want to control the basic functions of your PC from your phone, RDM + Remote Desktop is a sound choice.
