Just upgraded my PC to Windows Vista Home Premium. The transparent window title bars, task switching view etc are all part of the new Windows Aero interface - see more detail at www.microsoft.com/windows/products/windowsvista/features/....
See another photo at www.flickr.com/photos/dvdmerwe/670220152/ showing the live thumbnail view on the taskbar.
