Block untrusted XLL add-ins by default in Excel
The Excel team is pleased to inform you of a default setting change to Excel for Windows that will help defend your workbooks against potential threats from XLL add-ins. With this update, you will no longer be able to enable XLL add-ins in files obtained from the internet. This feature is available to users who are running Version 2302 (Build 16130.20128) or later.
