Microsoft warns Windows 11 install media bug blocks future security updates

Microsoft has issued a cautionary note regarding the installation of Windows 11 version 24H2 when utilizing physical media, such as CDs or USB flash drives. The concern arises specifically when the installation media contains security updates released between October 8 and November 12, 2024. In these instances, the operating system may not accept subsequent security updates after the initial installation.

Installation Media Recommendations

It is important to note that this issue does not extend to systems that receive updates directly through Windows Update or the Microsoft Update Catalog. Furthermore, installations that utilize the latest December 2024 security update are unaffected by this problem. To mitigate potential complications, Microsoft advises users to create new installation media that includes the December 2024 security update, which was released on December 10. This proactive measure ensures that systems can seamlessly receive future security updates.

For those who have already installed Windows 11, version 24H2, using media that contains the October or November updates, immediate action is recommended. Users should apply the December 2024 security update via Windows Update or the Microsoft Update Catalog to rectify the issue and restore the system’s capacity to accept future updates.

This advisory underscores the significance of utilizing up-to-date installation media when deploying operating systems, particularly in environments that depend on physical media for installations. Ensuring that installation tools are equipped with the latest security updates is vital for maintaining system integrity and ensuring ongoing support.

In addition, Microsoft has stated that it is actively pursuing a permanent solution to prevent such issues from arising in the future. Until that solution is implemented, users are encouraged to adhere to the recommended steps to keep their systems secure and capable of receiving essential updates.

Since the launch of Windows 11 version 24H2, users have encountered several challenges throughout 2024. Notable issues include the Disk Cleanup tool inaccurately displaying 8.63GB of removable update cache under “Windows Update Cleanup,” as well as a speaker volume spike problem, where users reported sudden increases in volume to maximum levels, particularly when utilizing external DACs like the Creative Sound BlasterX G6.

Maintaining an updated version of Windows 11 is crucial for ensuring system security, stability, and performance. Microsoft consistently rolls out updates to address vulnerabilities that could be exploited by cyber threats, thereby providing robust protection against malware and hacking attempts. These updates also encompass bug fixes aimed at resolving known issues, enhancing the system’s reliability, and preventing potential disruptions during use.
