xaml package registration

About this tag
The xaml package registration tag covers issues related to the registration and initialization of XAML-based components in Windows, particularly in Windows 11 24H2. A known regression affects Start Menu, Taskbar, Search, and other XAML-hosted elements after cumulative updates, causing failures during first-time logons or in non-persistent VDI environments.

The tag is relevant for IT administrators managing provisioning and for users encountering crashes or silent failures in XAML-dependent features.
