Microsoft has issued a critical advisory and urgent warning regarding an issue affecting the October and November 2024 updates for Windows 11, version 24H2. This issue could significantly impact the operating system’s ability to receive and apply future security updates when these updates are installed using physical media. This poses a severe risk to the security and stability of affected systems, and immediate action is necessary to prevent potential vulnerabilities.
What happens with the bug?
The issue arises when updates are installed via CDs or USB flash drives containing the affected versions. Systems updated in this manner may become incapable of accepting further security updates, exposing them to unaddressed threats. Microsoft has clarified that this issue does not affect updates delivered through the Microsoft Update service or the Update Catalog website. It is, therefore, critical to avoid using physical media created with the October or November 2024 updates for installation purposes.
Use the Microsoft Windows 11 December Update
To mitigate this risk, Microsoft recommends that IT administrators and users skip the October and November 2024 updates if physical media is the intended installation method. Instead, they should use the December 2024 update or any subsequent versions released on or after December 10. These later updates resolve the problem and ensure the operating system can receive essential future security updates. Microsoft has assured users that they are actively working on a permanent resolution and will provide additional information as it becomes available.
How had the update affected businesses?
The October 2024 release of Windows 11, version 24H2, introduced new features to enhance system functionality and user experience. Among the highlights was integrating AI-powered tools, including Copilot+, designed to transform Windows PCs into advanced AI-enabled platforms. Other notable features included support for Wi-Fi 7, an updated Quick Settings menu offering greater convenience, and new energy-saving and adaptive brightness controls to improve device efficiency. While these enhancements demonstrate Microsoft’s commitment to innovation, the release has also been accompanied by several reported issues, underscoring the importance of cautious update management.
What effect has the upgrade had?
Users of Windows 11, version 24H2, have encountered problems such as games displaying incorrect colours or failing to run when AutoHDR is enabled. Disabling AutoHDR has been identified as a temporary workaround for this issue. Additionally, some users have reported connectivity problems with integrated speakers, Bluetooth speakers, and Bluetooth headsets. These issues prompted Microsoft to impose an update block on specific devices to prevent the introduction of further complications.
What should companies do now?
For organisations, ensuring updates are applied correctly is paramount to maintaining robust security and system stability. Neglecting to address these issues promptly could expose systems to significant risks, including potential cyber attacks and operational disruptions. It is highly recommended that IT administrators review their update procedures to ensure compliance with Microsoft’s guidance and avoid the use of affected physical media.
