Microsoft has warned that using media support (CD or USB flash drives) to install Windows 11, version 24H2 may prevent the operating system from accepting security updates released between October 8 and November 12. This issue occurs when the installation media includes security updates from October 2024 or November 2024. It does not affect updates applied through Windows Update or the Microsoft Update Catalog, and installations using the December 2024 security update are not impacted. Microsoft is working on a permanent solution and recommends using the December 2024 security update for media-based installations. Additionally, users have reported various issues with the 24H2 update, including audio problems, application launch failures, game freezes, and performance issues with certain hardware and software configurations.
