Microsoft warns of Windows 11 bug blocking security updates
Windows 11 media installers face a bug preventing future security updates for some users.

Manually created Windows 11 installer media for October and November 2024 patches could leave systems unable to install future security updates. The issue impacts USB or CD installers for version 24H2 and may affect businesses, schools, and PC enthusiasts.
Microsoft clarified that systems receiving October and November updates via Windows Update or the Update Catalog remain unaffected. However, media-created installations require rebuilding with the December 2024 update, followed by a full reinstallation. Microsoft recommends ensuring December’s patch is included in new installation media.
The company acknowledged the issue on its known problems page and is actively developing a permanent fix. Other bugs in version 24H2 have also emerged, affecting audio devices, Outlook with outdated Google Workspace Sync, and certain Ubisoft games.
