Does Windows7 uses WPF? [closed]

Question

In Windows 7 (and Vista) is WPF used for the taskbar, the widgets, explorer or for anything else of the OS ?

Answer 1

No. The Windows Explorer doesn't use it, none of Windows built-in utilities use it, Office 2007 doesn't use it... AFAIK, the only MS app that uses WPF so far is the upcoming Visual Studio 2010
