Microsoft warns of a Windows 11 24H2 issue blocking security updates

Microsoft has warned of an issue affecting Windows 11 version 24H2 that blocks critical security updates.

The problem occurs when users install this version using media with the October or November 2024 security updates.

As a result, affected devices may not receive future security updates, leaving them vulnerable.

Details of the Issue

Microsoft states that the issue affects installation media with the October or November 2024 security patches.

Devices using the standard Windows Update process are not impacted. However, devices installed from faulty media may not receive future updates, putting their security at risk.

This issue does not affect older Windows versions or other platforms.

To avoid the problem, Microsoft advises users and IT administrators not to install Windows 11 version 24H2 using installation media with October or November updates. Instead, use media updated with the December 2024 security update or later, or use the standard Windows Update process.

For those who have already installed version 24H2 using the faulty media, Microsoft is working on a fix and will provide updates soon. Affected users should check Microsoft’s update page for more details.

This issue is part of a list of known problems with Windows 11 version 24H2, including audio issues, gaming glitches, and compatibility problems with third-party apps like Google Workspace Sync.

While many issues have been resolved or mitigated, this installation problem is a critical security risk. Microsoft is working with partners to fix it and will provide updates.

Users are encouraged to check for updates regularly and follow Microsoft’s guidelines for creating installation media.
