When a user taps the title bar, a pull-down list appears with icons that map to the notification or status icons in the title bar. When a user taps an icon in the pull-down list, this launches the existing associated action. For example, tapping the Volume icon in the pull-down list of the title bar launches Volume Settings.
OEMs can override the title bar items listed in the pull-down list. For example, if you replace standard volume settings with a custom volume event, when a user taps the associated icon, the title bar pull-down list will launch the customized volume setting. If you remove customized registry key settings, the default Microsoft application will appear when a user clicks the associated icon.
Not all items on the title bar pull-down list can be replaced with custom applications or events. You can customize task bar button handlers only. You cannot customize shell notifications and shortcut handlers.
 Note: |
|---|
| Changing the task bar events will not affect the associated title bar icons. For information about title bar icons, see Customizing Title Bar Icons on the Home Screen. |
Each of the applications listed in the pull-down list has a corresponding launch path. You can specify each of these paths by using the following values stored in the HKEY_LOCAL_MACHINE\Software\Microsoft\Shell\Rairegistry key.
The following table shows the keys and named values for each key.
