Add-ins are programs that run within Word and perform actions that Word doesn't provide. They can be pre-installed by third parties or downloaded by Word Users.

Since add-ins are separate programs, occasionally a Word add-in can encounter problems that slow down Word's startup.

Note: This content applies to the desktop versions of Word. Some features may not be available in Word for the web or mobile apps.
