About this tag
The XAML tag on WindowsForum.com covers discussions about a provisioning-time regression in Windows 11, version 24H2, where XAML-hosted shell components such as the Start menu, Taskbar, File Explorer, and Settings fail to initialize after cumulative updates from July 2025 onward. The issue is tied to a timing-dependent failure during provisioning, particularly affecting enterprise and non-persistent virtual desktop deployments. Microsoft has acknowledged the problem in KB5072911 and provided short-term mitigations while a permanent fix is developed. Threads explore the technical details of XAML package registration failures, the impact on IT administrators, and workarounds for affected systems.
