Is it possbile to change the background in Microsoft Office 2016/2013 so that it's not white. There's such a possibility in OpenOffice and I can easily adjust the background to light grey 15%.
You mean the change of the program theme or the background alone? Both can be easily changed in one place - you just need to go to the 'File' menu and there you'll find an item called Options.
I meant the theme of the whole program, thanks bro!
