From the list of backward steps :
- I found no way to hide the taskbar ==> permanent clutter. This is a step backward compared to both Win 7 and Win 8. Incredible. Found now workaround in Windows help. All the more incredible since any device (tablet or PC) do have a windows button reps. key to invoke, basically, the taskbar. So that key, which has been introduced ten years ago or so, is still looking for a justification.
EDIT : "hide the task bar automatically" is a proposed setting, but it does not work, at least on my M$ Surface laptop/tablet. It is apparently a bug, as the task bar would then hide parts of full screen windows (i.e. the system assumes that the task bar is hidden and sizes other windows accordingly, while in effect the task bar is displayed and hides parts of the application windows.)
- no way to display picks full screen and flip to the previous or next (using tactile screen or keyboard arrows), unless you hit "slideshow", but then you lose control.
- automatic re-orientation of screen according to orientation of device, most useful when displaying pics in portrait orientation, does not work on MS Surface
Fortunately it is still possible to have the welcome screen presenting applications by groups (as in Win eight), by forcing the device to start in tablet mode.
Maybe I'll find niceties, but none so far (note that I have been using Win 8 for two years, both on a M$ surface and a bigger laptop, with either keyboard and mouse or tactile screen - so the niceties already introduced by Win 8 do not count).
