Microsoft has issued a warning regarding potential issues when installing Windows 11 version 24H2 using physical media such as CDs or USB flash drives. The problem arises when the installation media includes security updates released between October 8 and November 12, 2024. In such cases, the operating system may not accept further security updates post-installation.

This issue does not affect systems that receive updates directly through Windows Update or the Microsoft Update Catalog. Additionally, installations using the latest December 2024 security update are not impacted. To avoid this problem, Microsoft recommends creating new installation media that incorporates the December 2024 security update, released on December 10. This ensures that the system can receive future security updates without hindrance.
