Microsoft has acknowledged a bug in Windows 11 that disrupts the functionality of Internet Explorer mode within Microsoft Edge for certain users, affecting the loading of legacy websites and applications. This issue primarily impacts organizations that rely on IE mode for older internal web applications. Microsoft is investigating the matter and developing a fix, but no timeline for resolution has been provided. Organizations are advised to identify affected internal websites, monitor the Windows release health dashboard for updates, avoid altering IE mode configurations, and report issues through Microsoft support if they impact critical applications.
