Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
I have the same problem with Office 2016 on Windows 10. Got new workstation in January and it was FINE. Then about 2 weeks ago an update was installed and now it keeps going back to colorful. I have it on black because it causes less eye strain. Oh well....guess I'll just sue Microsoft when the eye strain starts affecting my health...stupid idiots. Close the holes in your software....don't take away functionality.
