What are the default port numbers that needs to be changed in Windows?

Though changing default port numbers is "security by obscurity", I believe it at-least gives the admin a clear info whether an attack taking place is targetted ones or automated attacks by script junkies.

I use to change default RDP port in Windows Servers when they are exposed to the Internet.

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp\PortNumber

This is all you can do in order to harden by obscurity, as you say, without breaking any Windows core functionalities, as far as I know. At least regarding Windows core services. If running db servers such as MS Sql or Mysql you might change default port as well.
