xRDP on Kali Linux is an open-source implementation of the Microsoft Remote Desktop Protocol (RDP) server. It allows you to remotely access and control the graphical desktop environment of your Kali machine from another system using a standard RDP client, like the built-in Remote Desktop Connection on Windows or Remmina on Linux.

When installed and enabled, xRDP runs as a service and bridges the connection between the RDP client and the local X Window System (X11) on Kali. This makes it especially useful if you’re running Kali in a virtual machine or on a remote server and want to interact with the full GUI instead of just using SSH for command-line access. It supports multiple desktop environments (XFCE, GNOME, etc.), but XFCE is often recommended for better performance.
