Microsoft Confirms Windows 11 Bug Breaks IE Mode in Microsoft Edge for Some Users

Microsoft has confirmed a bug in Windows 11 that breaks Internet Explorer mode in Microsoft Edge for some users. IE mode is used to load legacy websites and web apps that still require Internet Explorer.

The bug stops these sites from loading properly. Microsoft acknowledged the issue on the Windows release health dashboard and says a fix is in progress. The problem mainly affects organizations that depend on IE mode for older internal web applications.

So far, Microsoft has not provided a fix or workaround beyond acknowledging the problem.

What the IE Mode Bug Does

IE mode in Edge is meant for loading older websites and web apps built for Internet Explorer, which is no longer available as a standalone browser. Many organizations still rely on IE mode for internal tools that have not been updated for modern browsers.

The confirmed bug prevents IE mode from working correctly for affected users, meaning those legacy sites and applications may fail to load as expected. Because IE mode is primarily used in enterprise environments, the impact falls mainly on businesses running older web-based software rather than general consumers.

Microsoft confirmed the issue on the Windows release health dashboard, which tracks known problems in current Windows versions. The company says it is investigating and working on a fix.

Until a fix is available, affected organizations may need to review which internal applications depend on IE mode and plan for the disruption. Microsoft has not published a temporary workaround.

What Affected Organizations Can Do

Organizations that rely on IE mode should assess the impact while Microsoft works on a fix:

1. Identify which internal websites and applications depend on IE mode in Edge, since those are the ones affected.
2. Monitor the Windows release health dashboard for updates on the fix and any official workaround.
3. Hold off on removing or replacing IE mode configurations, since the issue is a bug rather than a deliberate change to the feature.
4. Report the issue through Microsoft support channels if it disrupts business-critical applications, to register the impact.

Microsoft has confirmed the bug but has not released a fix or given a timeline. BleepingComputer does not specify which Windows 11 versions or updates introduced the issue.

Organizations affected by the IE mode failure should monitor the Windows release health dashboard for updates and the eventual resolution.
