Windows 11 Bug Breaks Internet Explorer Mode in Microsoft Edge

Microsoft has confirmed a bug in Windows 11 that breaks Internet Explorer mode in Microsoft Edge for some users. This issue affects organizations that rely on IE mode to load legacy websites and web apps that still require Internet Explorer.

The bug prevents these sites from loading properly, and Microsoft acknowledged the problem on its Windows release health dashboard. The company says a fix is in progress but has not provided a temporary workaround or given a timeline for resolution.

IE mode is primarily used in enterprise environments, so the impact falls mainly on businesses running older web-based software rather than general consumers. Organizations affected by this issue should assess the impact and review which internal applications depend on IE mode.
