This Monday, 13th of January 2025 was a bad day for sysadmins. Outlook and other Microsoft 365 / Office Apps would crash upon start because of a new update pushed by Microsoft. The message says something about react-navis-win32.dll missing. The only fix is to install the December 2024 Updates to fix the issue.

This configuration XML File install the December 2024 updates. Beware: This configuration is for Windows Server 2016 RDS and note that automatic updates are disabled.
