In a surprising twist for Windows 11 users, Microsoft has issued a crucial warning about a significant bug that prevents some installations from receiving essential security updates. This issue primarily affects those who create their own installation media, such as USB drives or CDs, using the October and November patches.

The company highlighted that if users install Windows 11 version 24H2 with these specific updates included, their devices might end up in a precarious situation where they cannot accept any future security updates. This is particularly concerning for professionals who set up PCs in business or educational settings and for tech enthusiasts who have recently built their custom machines.

According to Microsoft’s known issues page for Windows 11, the glitch arises when the installation media is created featuring security updates released between October 8, 2024, and November 12, 2024. However, it’s important to note that systems updated through Windows Update or downloaded from the Microsoft Update Catalog remain unaffected.

To mitigate this issue, affected users need to rebuild their installation media, this time including the December 2024 patch update, which became available on December 10th. Microsoft strongly recommends ensuring that any media used for installing Windows 11 version 24H2 includes this crucial update to avoid complications.

In a broader context, Bleeping Computer has reported that Windows 11 version 24H2 isn't just facing this security update dilemma; it also suffers from various other bugs. Users have experienced audio device compatibility issues, problems with launching Outlook when paired with outdated Google Workspace Sync, and compatibility challenges with certain Ubisoft games. Fortunately, fixes are gradually rolling out for these problems.

As of now, Microsoft is actively working on a permanent solution for the security update issue. If you’re one of the affected users, it’s time to check your Windows installation media and ensure you’re protected from potential vulnerabilities. Stay tuned for updates, as this situation develops!
