Microsoft is warning users that some manually created Windows 11 installation media may contain a bug that could prevent new computers from receiving future security updates. This applies to USB and CD media made with the October and November patches, which may be relevant for professional users who set up computers in business and educational settings, as well as for enthusiasts who have recently built their own computer.
This does not affect computers that have received the October or November hotfixes through Windows Update or the Microsoft Update Catalog website.
To resolve the issue, you will need to update your Windows 11 media installers to include the December 2024 update (released on December 10) and reinstall Windows. (To avoid this issue, Microsoft recommends that “the media used to install Windows 11 version 24H2 contains the December 2024 monthly security update.”) Microsoft says it is working on a permanent fix.
Bleeping Computer reported that Windows 11 24H2 also had other bugs, including issues with certain audio devices, problems running Outlook with outdated Google Workspace Sync, and others. There was also a strange 24H2 compatibility issue with some Ubisoft games that is slowly being fixed.
