Py-RDP-Patcher is a tool made in python to patch the termsrv file to allow simultaneous RDP sessions
This script only requires the art library which is installed by executing :
pip install art
Requirements:
Python3, Windows
Limitations:
For now this script only supports windows 10 version 1909,1903,1809,1803 and 1703 (to know your version type this into powershell Get-ComputerInfo | select WindowsProductName, WindowsVersion) if your windows version is not supported and you know the corresponding hex code you can modify this script to support your version. I will not go into details on how to do it but the script is pretty straightforward if you know just a bit of python it should be easy to do.
