How exactly does Windows launch packaged (appx or msix) apps?
For example, consider the settings app (ImmersiveControlPanel, lives in C:\Windows\ImmersiveControlPanel) on Windows 11
<Applications>
<Application
Id="microsoft.windows.immersivecontrolpanel"
Executable="SystemSettings.exe"
EntryPoint="AppObject.EntryPoint">
[...]
</Application>
</Applications>
Its Appxmanifest specifies the executable and a class id as entry point.
What exactly does happen between searching and clicking the settings app in the startmenu or invoking with e.g. ms-settings:settings and the settings app window showing up?
It magically works, but i failed to find any documentation that goes a bit more into detail.
