There are some user with issues on build 16170 as the GUI of the programs does not start correct.
The Screen is almost white with no info.
I had this on a Surface Pro 4 m3.
I changed Computer\HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Graphics\DisableHardwareAcceleration from 1 to 0 and the issue was resolved.
Might help someone.

On a HP Pavilion 17 this did not happen. The registry key does not exist on that machine.
