Maybe we need to do this for all modals.

protected GitModuleForm([NotNull] GitUICommands commands)
    : this(commands, enablePositionRestore: true)
{
    ShowInTaskbar = true;
}

As I mentioned in an issue comment: I do not want to see modal dialogs in the Task Switcher list in addition to the (GE) main window.
As far as I know, this is has been "solved" in Win10. Win7 is out of maintenance.
