Configure Windows 10 taskbar (Windows 10) | Microsoft Docs
Remove default apps and add your own
By adding PinListPlacement="Replace" to <CustomTaskbarLayoutCollection>, you remove all default pinned apps; only the apps that you specify will be pinned to the taskbar.
If you only want to remove some of the default pinned apps, you would use this method to remove all default pinned apps and then include the default app that you want to keep in your list of pinned apps.
