Word 2013 on a A10/8g RAM  running great under 8.1  Upgraded to Windows 10 this AM and now editing just crawls- it is painful.

Got to be something somewhere that didn't transition? 

Thoughts?

Hi,

Do you mind tell your Office 2013 version id? I'm using 15.0.4737.1003 in Windows 10, it works normal as before (Windows 8.1).

Please make sure you have installed all the latest update patches of Windows 10 and Office.

Then, we can update the Video card drivers, it also might cause the performance issue.

Hope it's helpful.
