Windows 7 Taskbar: Capture thumbnails

Is it possible to capture the 'live' thumbnails from the Win7 taskbar? I want to display this preview (of another window) in my application, but how to extract those 开发者_运维问答previews using .NET?

Yes.

MSDN Magazine explains how.
You can also use the Windows API Code Pack, which handles the interop for you.

There's a System.Windows.Shell namespace in .NET 4 that enables you capture thumbnails, etc. See Link
