A bug in the recent installation media for Windows 11 prevents users from installing the latest security updates if the media includes the October 2024 or November 2024 security patches. Microsoft has acknowledged that this issue occurs only when using installation media, such as CD and USB flash drives, created in the last few months with these updates. The problem does not affect devices that receive the updates via Windows Update or the Microsoft Update Catalog. Users are advised to avoid installation media with the October or November 2024 patches and instead use media with the September 2024 or December 2024 patches. Some users have found success using the "Fix Windows Update" button in the Recovery section of Windows Settings, and the official Windows 11 ISO tool can create an installation image without the problematic patches.
