install media bug

The install media bug is a critical issue affecting Windows 11 systems set up using manually created USB or CD installer media that includes the October 2024 or November 2024 updates. Microsoft has warned that such installations may be permanently blocked from receiving future security updates, leaving systems vulnerable. This bug specifically impacts DIY installers and users who create their own installation media. The problem does not affect systems updated via Windows Update or those using official Microsoft media without the affected updates. Users are advised to avoid using manually created media with those updates until a fix is released.
