To make it hackers less easy to connect with RDP to our servers or desktops we can change the port for this and I really recommend it to every one.

Simply choose a random number and than follow the instructions here.

This can be achieved by using regedit to manipulate the registry

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\TerminalServer\WinStations\RDP-Tcp\

Enter here for the PortNumber a new decimal value (switch from hexadecimal to decimal).

Pay attention to not forget to adapt your firewall rules with the new ports and your port forwarding rules within your router.
