Specifies the icon used for the shortcut created on the taskbar when the user chooses to pin an application to the taskbar or launch a new instance through its button's Jump List. This is the icon used for the taskbar group and is shown for a pinned application whether that application is running or not. This should be specified in one of the following formats:
- Standard resource format, such as "%systemdir%\system32\shell32.dll,-128". The '-' character before the resource ID is required. Do not use the '@' character at the front of the path string.
- Direct path to an icon file, such as "%programfiles%\Microsoft\Notepad\Notepad.ico,0". Note that because .ico files can contain multiple icon resources, a resource ID is required in the string. If the .ico file is a single image, use "0" (without the '-' character) as the resource ID.
System.AppUserModel.RelaunchIconResource is an optional property. If it is not set, the icon of the target of the relaunch command (System.AppUserModel.RelaunchCommand) is used. However, because that can lead to undesired results, we strongly encourage you to provide an icon explicitly through this property.
This property is used only if a window has an explicit Application User Model ID (AppUserModelID) (System.AppUserModel.ID, set through SHGetPropertyStoreForWindow). If the window does not have an explicit AppUserModelID (System.AppUserModel.ID), this property is ignored and the window is grouped and pinned as if it were part of its owning process. For more information on the application of explicit AppUserModelIDs and their effect on taskbar pinning, see Application User Model IDs (AppUserModelIDs). This property is meant to be used by applications or windows that want to provide non-default relaunch information. For more information, see System.AppUserModel.RelaunchCommand.
If an explicit AppUserModelID is set on the window, but this property is not set, the system attempts to find a shortcut with the same AppUserModelID, and pins that shortcut to the taskbar to represent the window. If no such shortcut can be located, then the backing executable of the process that owns it is used.
Note This property is ignored if System.AppUserModel.PreventPinning is set. This enables an application to control the grouping of its windows by assigning them explicit AppUserModelIDs but preventing those windows from being pinned.
To set this property on a window, use SHGetPropertyStoreForWindow to retrieve the window's property store, and use the methods of that retrieved IPropertyStore object to set the System.AppUserModel.RelaunchIconResource property of that window.
