Overview
Microsoft introduced a new naming convention for Windows Updates beginning with Windows 24H2 and later: Microsoft Blog - Simplified Windows Update Titles
As a result, updates that were previously labeled 'Cumulative Update for Windows' may now appear with the' Security Update' naming convention. You may notice these new titles in the Automox console.
This change comes directly from Microsoft and affects all vendors that surface Windows Update metadata.
What Changed
Microsoft’s simplified naming approach consolidates 'Cumulative Updates' into 'Security Update' titles for devices on Windows 24H2+.
Older Windows builds may still show the previous naming, so you may see both styles in mixed environments.
Microsoft Update Catalog and WSUS may still show older naming conventions.
Impact in Automox
- Automox displays update titles exactly as Microsoft provides them through Windows Update.
- Devices on Windows 24H2+ will display 'Security Update' instead of 'Cumulative Update for Windows'.
- Microsoft Update Catalog and WSUS may still display older naming conventions, resulting in discrepancies across tools.
Recommended Actions
- Review Patch Policy Criteria: Review all Patch Only, Patch Except, and Advanced Patch policies for title-specific filters like “Cumulative Update”. No action is required if you use the Automox Patch All policy.
-
Update Filtering Logic: If your policies filter by update name, consider adjusting the criteria to align with the new conventions: Creating a Patch Policy
- Add "Security Update": You must include "Security Update" in keyword-based Policy filters to catch the monthly cumulative updates (e.g., 2025-10 Security Update) for Windows 24H2+ devices.
- Add "Preview Update": If you deploy optional non-security fixes, these are now labeled "Preview Update" rather than "Cumulative Update Preview."
- Remove Architecture Constraints: If you were filtering by "x64" or "version 23H2" for Windows 24H2+, be aware that these details are often removed from the display title in the new format.
- Review and Monitor Pending Updates: Closely monitor the patches awaiting installation or approval in your environment after November 9, 2025 to confirm that the correct updates are being applied.
