Microsoft has issued an advisory for Windows users regarding potential issues when updating to Windows 11 version 24H2 using external media. If users create installation media that includes the October or November 2024 security updates, their devices may end up in a state where they cannot accept further Windows security updates. This problem does not affect devices that receive updates through the standard Windows Update process. The issue is reported to impact only a small number of users, and Microsoft recommends using the Media Creation Tool to create new media and reinstall the operating system if users encounter update problems.
