While I like the new Office, I honestly loath the “design-guru” who decided to cross-fade, smooth transitions and in general make everything you do slow down, so you can look at the nice little flow of the programs.
The most irritating, for me, the Word typing animations and Excel cell-change. Luckily you can turn them off.
Go into your registry: [HKEY_CURRENT_USERSoftwareMicrosoftOffice15.0CommonGraphics]
Create a new dword: “DisableAnimations”=dword:00000001
(I also had to create the Graphic-key)
Reboot and enjoy efficiency once again.
