New taskbar icon when opening a window in WPF

Question

I have an application that opens another window on some action. I have set a separate icon for the new window, and a new item appears in the taskbar, but the item is stacked behind the original app window. Is it possible to show the new window unstacked in the task bar? So I would have 2 icons in the task bar.

Please see the image for my problem.

Thanks to Xaruth for pointing me in the right direction I found the answer. It seems widows uses an ApplicationID to determine if a window should be grouped with another one.

If you download the Windows API Code Pack you can set the ApplicationID of the window you want to appear as a separate taskbar icon.

Here's the code:

TaskbarManager.Instance.SetApplicationIdForSpecificWindow(
    new WindowInteropHelper(wind).Handle, "Gx3OptimisationWindow");

Where wind is the window you want as a separate icon and GX3OptimisationWindow is the new ApplicationID.
