I can confirm that the touchbar displays screen brightness, keyboard brightness and volume controls. If you press the FN key the standard function keys display on the bar.
[doublepost=1479299308][/doublepost]However, I have a different problem in boot camp. For whatever reason my screen flickers on and off, constantly. To the point that Windows is unusable. If I move my mouse continuously the screen stays on. Tried running Windows updates...no luck. I'll try deleting the bootcamp partition and re-installing with the Windows 10 Anniversary edition to see if by some chance that fixes things. Not good though...very disappointing. I didn't have this issue with my non TB 2016 rMBP.
