Get handles of all windows in the taskbar

I'm quite new to the Windows API and I'm trying to find the handles of all the windows which appear in the taskbar.

So far, I have managed to:

I have tried getting all child windows of the desktop window, which gives me nearly 900 window handles! So I tried to filter them down, by getting only visible windows and only windows whose title is longer than 0 characters, but I'm still way off - with 68 windows??

So could some Win API expert enlighten me as to how you do this please :-) and also possibly explain why there are so many windows?

Edit:

private static bool HasAppWindowStyle(IntPtr handle)
{
    return (GetWindowLong(handle, GWL_EXSTYLE) & WS_EX_APPWINDOW) != 0;
}

The exact algorithm is not documented, I came up with some pseudo code in this answer that does an ok job.

Top-level windows that you find with EnumWindows and have taskbar buttons will have the WS_VISIBLE and WS_EX_APPWINDOW style flags turned on.

Did you see FindWindowEx sample? Also you can filter them to have a text on it, I think the windows you are see is the Desctop items (I'm not sure) but remove some item from desktop and see the changes.
