Today I decided to upgrade my home computer to Windows 8 Pro. One thing you have to know is that this is a very critical system for us at home. It runs the entertainment system and most importantly feeds our TV system (XBox 360) in the living room. I was specifically nervous about the fact that the TV signal for the Media Center comes from a powerline connected devolo dLAN TV Sat PC device (that actually sits on the top floor of our house).
