Microsoft decided to animate the cursor in Office 2013. The end result is that you feel your cursor doesn't blink while you are typing. This is mainly because your cursor moves across the screen smoothly as you type. It looks really weird to me…
In order to fix that, you need to save the following code segment as a
.reg file, and import it into Windows registry.
Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\15.0\Common\Graphics] "DisableAnimations"=dword:00000001
For Office 2016 (Office 16), the code segment is the following:
Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Common\Graphics] "DisableAnimations"=dword:00000001
