Strange. I have 2 DELL monitors connected with daisy chain to docking station and every morning I just put my surface to docking station and everything works.
Experienced only one problem: skype does not switch to external micro (I have webcam connected to docking) and I need to restart skype...
Windows installed intel drivers again via own update service. and you need to uninstall it and install Intel provided version.
But I`m expirienced similar problem and cannot find the way to disable windows autoupdate for this driver. Maybe someone know how to do it.
Yes, I`m running windows 10 right now and fan works the same as on previous OS version.
But I made clean windows 10 install because had problems with drivers and VirtualBox.
You may try to make factory reset.
