Recent reports reveal a bug in Windows 11 24H2 that is disrupting security updates for certain users who installed the operating system using specific media like a USB stick. The issue stems from flawed installation packages based on the October or November 2024 security updates, preventing affected devices from receiving further Windows security updates. Microsoft has acknowledged the problem and recommends reinstalling Windows 11 24H2 using a newer version to resolve the issue. Users are advised to ensure they are using the latest installation media to avoid encountering this bug in the future. If already impacted, a reinstallation with December 2024 version or later is recommended to restore security updates. It is advisable to back up personal data before undertaking the reinstall process. While not all users may experience this issue, staying vigilant for future occurrences is advised.
