+- **Windows Terminal gets its framework package registered first.** Terminal is
+  an MSIX that depends on `Microsoft.UI.Xaml.2.8`, which winget installs for it
+  from a pinned build (8.2310.30001.0). When a *newer* build is already on the
+  machine but not registered for the account running the setup, Windows
+  declines to stage the older one, winget then tries to register a package
+  that is not there, and what it prints is `Installer failed with exit code:
+  0x80070002 : The system cannot find the file specified` — with Terminal
+  itself never attempted, on every run. So the batch file first registers the
+  build that is already there (`Add-AppxPackage -RegisterByFamilyName`, no
+  elevation needed), and winget then finds the dependency met. With none on
+  the machine it does nothing, and winget installs the framework as usual.
