We’ve had an issue with Word 2013 lagging and freezing.
Unable to scroll or type or access an open document for 30 seconds to a minute. I reviewed all the recent updates and found that KB3114717 was on the affected machines.
Update 3114717 is no longer available because it causes Microsoft Office 2013 apps, such as Microsoft Word and Microsoft Outlook, to slow down or freeze.
Once uninstalled Word was back to normal operation.
