It’s almost impossible to overstate the usefulness of remote desktop access for Windows PCs. Simply put, it lets a user or administrator on one Windows PC, called a client machine, establish a remote session on another Windows PC, called a server or host machine.
Microsoft’s Remote Desktop Protocol (RDP) is the foundation on which various built-in Windows remote access tools rest. This secure network communications protocol supports both the old-school Remote Desktop Connection application and the modern Remote Desktop app, both shown in Figure 1 below.
Using available network connections between client and host via RDP, these programs let the client user open a window that displays some chosen remote desktop. With a remote desktop session up and running, that user can operate the targeted remote desktop almost as if they were sitting in front of it.
