My tool was working in both Vista and XP and we want to modify the message boxes to look like Vista style message boxes. Once we modified, things looked cool in Vista, but it stopped working in XP. Figured out the TaskDialogs are not backward compatible with XP and then found this implementation that promised of Vista Style Dialogs working with XP. hence bookmaking this site.
During the Google search i found this creative About Box which according to me is cool and very useful.
