I bought a new notebook and upgraded from windows 8.1 standard to pro so I can rdp into it.
I use rdp because it's easier to connect this way and take advantage of my desktop screens and keyboard/mouse.
When I am connected via RDP, the logonui.exe process takes more and more memory until the machine is unusable. I kill the process (or process tree) and it re-starts climbing in memory consumption once again.
It only happens when connected via RDP from my windows 7 Pro desktop.
