Clearly, I figured too, this is just a normal modern search app, Cortana might still be possible to enable, hopefully.
However this hints, that Cortana will be heavily Bing Search based... The Cortana could be possibly enabled only, if there is another EXE in: c:\Program Files\WindowsApps\Microsoft.Cortana_1.2.0.0_x64__8wekyb3d8bbwe or c:\Program Files\WindowsApps\Microsoft.Cortana_2014.913.601.3539_neutral_~_8wekyb3d8bbwe (I didn't checked.)
is administrator_ploc the new administrator account. sysprepped and used an old unattend.xml and have both administrator and administrator_ploc.
Does anybody know how to disable driver signing enforcement in the TP of the server version? This one doesn't have a charm bar (neither via win+c, nor via the upper right corner hovering)...
