Confirmed: The latest Windows 11 updates might break Start, Taskbar, more

Microsoft has confirmed a new issue that is impacting Windows 11 PCs which might see integral UI elements such as the Start menu and Explorer fail to load in or crash after being provisioned with the latest security updates. The company says this issue mostly impacts enterprise PCs, and is “unlikely” to occur on personal devices.

The support document published by Microsoft says that “After provisioning a PC with a Windows 11, version 24H2 or a Windows 11, version 25H2 monthly cumulative update released on or after July 2025, XAML-dependent modern apps such as Explorer, the Start menu, SystemSettings, Taskbar and Windows Search might experience difficulties.”
