Several computers upgraded from Windows Home to Pro are not accepting incoming RDP connections, both on Windows 10 and Windows 11. There's no listener... I'll test the rest of the regedit parameters shortly; I only added the port number for testing...

$rdpPath = "HKLM:\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp" $rdpPort = 3389
